That depends on the data, the To File block writes data as a matrix of two or more rows. The block writes one column to the MAT-file for each time step. The first element of the column contains the simulation time. The remainder of the column contains scalar or vector data for the time shown at the top of the column.

For example if you save to one mysimdata.mat file and use the variable ans for the ouput:

load('mysimdata') %load the saved data
s=2; %second row got the signal
plot(ans(1,:),ans(s,:)) %first row is the time

if you got more signals in there

s=3; %third row got the data you want to plot
plot(ans(1,:),ans(s,:))

more signals just add one to s and plot it

plot(ans(1,:),ans(s,:))

what to do if this input file itself is showing error?
