Returning array

To use a worksheet formula that returns an array result, you must first select a suitable range of cells, with dimensions (R x C) large enough to accommodate the returned array, then type the formula in the formula bar, and finally enter the formula by pressing CONTROL+SHIFT+ENTER. Excel will indicate that the formula is an array formula by enclosing it in braces and will enter the array formula in all the selected cells. 

A few of Excel s worksheet functions are array functions, that is, they return arrays as results. One of these, the LINES statistical function, is described in Chapter 11. 

If you use a worksheet function within VBA that returns an array, the lower array index will be 1. Such worksheet functions include LI NEST, TRANSPOSE, MINVERSE, MMULT. Other functions that return arrays include the VBA function Caller when used with a menu command or toolbutton. 

The smiles to symbols and smile to bonds functions return arrays of values. In the sample output above, the smiles to bonds output has been truncated for easier viewing. Some client programs may expect this information as separate rows, as if they were records in a file. These arrays may be cast into that form by using a plpgsql function that returns elements of an array as rows. This is shown in the next section. 

The ICapeThermoMaterialObJect methods are used to obtain and calculate properties associated with a material object. This object must have direct access to the data contained in the property package object to be able to get properties for pure components from the property package. In the current implementation, the material object contains a collection of components exposed through the IComCollection interface described above. Each component contains the following data concentration, constant properties, and non-constant properties. The material object also contains the temperature and pressure data which completes the definition of the system and mixture properties calculated for the system. The material object s Componentlds and GetComponentConstant methods enumerate the collection and return arrays of the names of the components present in the material object and their properties. 

Afterwards, the accumulated quantities have to be normalized by the number of a and b pairs used for each value of 1. The following code fragment implements the subroutine that takes the values of 4(u) and B ii) stored in the arrays a, b, and returns array c, containing the normalized correlation function values for times from 0 to mcor St. It also calculates the averages of A i) and B i) a av and b av and their root mean squared deviations delta2a, delta2b, to obtain normalized correlation functions. A and B are available for time slices 0 to m.

Recently, there has been a growth of interest in the development of in vitro methods for measuring toxic effects of chemicals on the central nervous system. One approach has been to conduct electrophysiological measurements on slices of the hippocampus and other brain tissues (Noraberg 2004, Kohling et al. 2005). An example of this approach is the extracellular recording of evoked potentials from neocortical slices of rodents and humans (Kohling et al. 2005). This method, which employs a three-dimensional microelectrode array, can demonstrate a loss of evoked potential after treatment of brain tissue with the neurotoxin trimethyltin. Apart from the potential of in vitro methods such as this as biomarkers, there is considerable interest in the use of them as alternative methods in the risk assessment of chemicals, a point that will be returned to in Section 16.8. 

Return to the case of LiF. Lithium ionizes readily, but has little affinity for electrons (I = ionization energy = 5.4 eV and A = electron affinity = 0eV.). On the other hand, fluorine is difficult to ionize, but has considerable electron affinity (I = 17.4eV. and A = -3.6eV.). Thus, when Li and F atoms are close neighbors, electrons can transfer to make Li+ and I. These then attract electrostatically until compression of their ion-cores prevent them from contracting further. In a solid crystal, there are both attractive +/- pairs, and repulsive (+/+ as well as -/-) pairs. However, for large arrays, there is a net attraction. This can be shown most simply by examining a linear chain of +q, and -q charges (Kittel, 1966). 

The preceding argument works also for the T i hypersurface, but exactly in the opposite sense. Now loose geometries are more favorable and this is where the biradicaloid minima should be sought (for instance, 2, not 4). These minima in Ti will typically allow considerable freedom of motion such as bond rotation, since there now is no rigid geometrical requirement such as a need for a cyclic array of orbitals was in the singlet case. Also, return to So is spin-forbidden and may be relatively slow,... 

The calculation is performed in terms of degrees Celsius, including values both above and below zero. It is not convenient, therefore, to use the relative increment of temperature as a test for step size in subroutine CHECKSTEP. I use absolute increments instead. At the end of subroutine SPECS, I set incind equal to 3 for all equations, limiting the absolute increment in temperature to 3° per time step. Zonally averaged heat capacity as a function of latitude is calculated in subroutine CLIMINP in terms of land fraction and the heat capacity parameters specified in SPECS. It is returned in the array heap.
