I'm trying to use use Simulink's "From File" block and I can't get it to read any of the .mat files I create.

I have two vectors of equal length, one is a timestamp, the other is a data value. The vectors are quite long, but as an example, I'll use the following:

    t = (1/32).*[ 1 2 3 4 5 6 7 8 9 10]';
    v = [1.123 1.125 1.235 1.443 1.135 1.123 1.125 1.235 1.443 1.135]';

I've tried the following .mat files:

    b = timeseries(v, t);
    save('b.mat','-v7.3')

and:

   b = [t,v];
   save('b.mat','-v7.3')

both ways I've tried it I get the following error message:

"Simulink does not support loading the input data in file 'b.mat'. Simulink can only load two-dimensional arrays or timeseries objects. The array must consist of one-dimensional, double, noncomplex samples. To load data having a different type, complexity, or dimension, use a timeseries object. For either an array or a timeseries object, at least one sample point is necessary."

How do I get these two vectors into a format that Simulink can read? Thanks for your help.
