Array assignment

A 1-DIMENSIONAL ARRAY ASSIGNED TO A WORKSHEET RANGE CAN CAUSE PROBLEMS... 

Manipulating arrays, assigning values to arrays and forms of expression for array (bit-string) literals are discussed in Chapter 5.

Except for the phase-contrast detector in STEM [9], STEM and SEM detectors do not track the position of the recorded electron. The spatial information of an image is fonned instead by assigning the measured electron current to the known position of the scaimed incident electron beam. This infomiation is then mapped into a 2D pixel array, which is depicted either on a TV screen or digitalized in a computer. 

Figure Bl.19.14. A sequence of STM images taken during tire construction of a patterned array of xenon atoms on a Ni(lOO) surface. Grey scale is assigned according to the slope of the surface. The atomic structure of the nickel surface is not resolved. Each letter is 5 mn from top to bottom. (Taken from [ ], figure 1.)...

Assignment—As>s gn a value, either a constant or a computed value, to a variable, an array element, a node, or a field. 

Array—May have more than one dimension number of dimensions and type are assigned at declaration and may not be changed values are assigned to array elements (which must be of same type) as they are to variables. 

Assignment statements—Assign values by numerical or character constants, by expressions (see Table 1-29 for arithmetic and set operators), or by input to variables, array elements, and fields... 

An ANN is an array of three or more interconnected layers of cells called nodes (much like columns of cells in a spreadsheet). Data are introduced to the ANN through the nodes of the input layer. For instance, each input layer node can contain the relative intensity of one of the m/z values from a bacterial pyrolysis mass spectrum. The output layer nodes can be assigned to iden-... 

Since the microarray spot images have many different sizes and shapes and some of the spots may not be located at the central position, addressing is essential to find the centre of the spots. In order to ensure accuracy of the measurements, an automatic spot detector is used to calculate the spacing between rows and columns of spots, the overall position of the array in the image and the spot size so that coordinates can be assigned to each of the spots in the array. 

With systems of increasing complexity, it becomes more and more difficult to keep track of which elements of the Y and YP arrays correspond to which physical variables, and such confusion leads to errors. I find it helpful to assign names to the variables that remind me what they are and relate these names to the elements of the y array in the subroutine DEFINITIONS. I call DEFINITIONS whenever I need current values of the dependent variables, but I can write expressions like those for yp in subroutine EQUATIONS using names rather than numbers.
