creating vector in matlab fcn bock

hi, i wanna to create a vector in matlab fcn block, that s my Code:

    function y = fcn
    e = 160;
    s = 45;
    vector = (s:e);
    y = vector

but i get this error: Output 'y' (#4Cool has variable size but the upper bound is not specified; explicit upper bound must be provided.

can u guys help me to solve that?

Hi!

I see no problem. Pasting your code in a function file and executing

result = fcn;

gives a resulting vector ranging from 45 to 160.

Hi, thank for the answer. But what do u mean with "Pasting your code in a function file and executing" ???

Hi!

If you have trouble defining functions in Matlab, start here: http://www.mathworks.com/help/matlab/matlab_prog/create-functions-in-files.html

Please use coder.varsize to define an upper-bound for the output variable as I have previously explained here. You also need to configure the MATLAB Function block for a variable-size output.

For this particular piece of code, variable-sizing should not be needed as the end points are constants. This example works fine for me in a recent version. What version of MATLAB and Simulink are you using?

You can find this out using the ver command: >> ver
