functionreadReal_m

Information

Syntax

result = readReal_m(fileName, name);

Description

This function demonstrates how a function can be implemented that reads the value of a parameter from a Matlab script-file. The idea is to keep parameters in Modelica and in Matlab/Simulink up to date. The function performs the following actions:

1. It opens file "fileName" and reads the lines of the file.
2. If a line starts with "% " or "// " or " ", it is skipped.
3. If a line starts with "name = expression" and the "name" in this line is identical to the second argument "name" of the function call, the expression calculator is used to evaluate the expression after the "=" character. The expression has to be terminated with a ";". After the ";" a comment can follow.
4. The result of the expression evaluation is returned as the value of the parameter "name".
