Dear all,

I am getting a syntax error in Simulink in a Fcn block:

u(strmatch('Name',OutList))

Error:

    Error using Run_Simu (line 16)
    The expression: u(strmatch('Name',OutList))
    in 'Directory of the file'
    has a syntax error    Error using Run_Simu (line 16)

I need to find Name from a string array in OutList (sometimes the order of the strings change, so that "strmatch"). The error is displayed only the first time. But if I need to implement the simulink model in a loop it is imposible due to the error.

How can I avoid the error or find the string in another way?

Thanks in advance, JOE

You cannot use the 'strmatch' function inside the Simulink 'Fcn' block. The 'Fcn' block only supports Mathematical functions: http://www.mathworks.com/help/simulink/slref/fcn.html

You can instead use the Interpreted MATLAB Fcn block: http://www.mathworks.com/help/simulink/slref/interpretedmatlabfunction.html
