Function statement

It can be synthesized with the MATLAB function feedback (). As an illustration, we will use a simple first order function for Gp and Gm, and a PI controller for Gc. When all is done, we test the dynamic response with a unit step change in the reference. To make the reading easier, we break the task up into steps. Generally, we would put the transfer function statements inside an M-file and define the values of the gains and time constants outside in the workspace. 

You can specify the data type of an argument passed to a Function procedure by using the As keyword in the Function statement. For example, if the Function procedure MolWt has two arguments, formula (a string) and decimals (an integer), then the statement... 

This appendix lists selected VBA keywords (reserved words) for functions, statements, methods and properties. See Excel s On-line Help for a complete list of keywords. 

This listing of VBA functions, statements, methods and properties will be useful when creating your own macros. For each VBA keyword, the required syntax is given, along with some comments on the required and optional arguments, one or more examples and a list of related keywords. See Excel s Online Help for further information. 

The second way to pass parameters is to use list the parameters in the function statement of the m-file. For example, the m-file... 

Each programmed department should be described in writing by including a written functional statement. Department h th care staff are well equipped to supply this information, which should include... 

Power is the product of volts and amps supplied to the cell (or cells), with a 5% addition for transmission losses. The current / can be calculated as the product of the area S and the current density /, and as the sum of the anodic and cathodic potentials, E and E c, the resistance in the separator (if any) Vd, and the potential drop in the electrolyte, which is dependent on i and the resistance of the electrolyte R. This dependence on functional process parameters is encapsulated in the functional statement of Eq. (6.61) ...

Fortran implementation. Equation 21-77 is easily programmed in Fortran. Because the implicit scheme is second-order accurate in space, thus rigidly enforcing the diffusive character of the capillary pressure effects assumed in this formulation, we do not obtain the oscillations at saturation shocks or the saturation overshoots having S > 1 often cited. The exact Fortran producing the results shown later is displayed in Figure 21-5 and in several function statements given later. For convenience, the saturation derivatives F (Sy ) and G (Sy ) are denoted FP and GP (P indicates prime for derivatives). 

Derivatives of F, and G with respect to water saturation can be easily taken by introducing function statements that define the differentiation process. We now discuss typical calculations, designed to test the properties of the scheme. 

Let us now discuss specific calculations. In this very first example, we set our mud filtration invasion rate identically to zero, using the function statement... 

To find the maximum point we, again, use fminunc but this time with a minus sign. Notice from Fig. 3.7 that the maximum lies at around x = 1.0. However, you have to add a minus sign to the function statement within the M-file itself. Thus, the funczero m-file becomes ...
