Simulink with the data from the workspace.

Started by Lei Shi ●July 30, 2002

Dear all,

I want to run a simulink with the data from the workspace. I use the following the following command lines:

    f=i+3.5;
    t=(0:0.016:50)';
    u=sin(2*pi*f*t);
    ut=[t,u];

sim('try_3');

and I set the parameter 'data' of block 'from workspace' as 'ut'. However, it occurs error information as following:

??? Error using ==> sim
Error evaluating parameter 'VariableName' in block 'try_3/From Workspace': Undefined function or variable 'ut'.

Error in ==> E:\Documents and Settings\TDYS\My Documents\Research\Work\FFT&DFT\test_fft.m
On line 9 ==> sim('try_3');

I don't know why 'ut' is undefined and how to defind it?

Thanks a lot.
