Replacing Input Signal Data. New data for a From File block can be placed in a

standard MATLAB MAT-file. As in Simulink, the From File block data must

be stored in a matrix with the first row containing the time vector while

subsequent rows contain

u vectorsasinputsignals.Aftergeneratingand

compiling your code, you can type the model name

rsimtfdemo at a DOS

prompt to run the simulation. In this case, the file

rsm_tfdata.mat provides

the input data for your simulation.

For the next simulation, create a new data file called

newfrom.mat and use this

to replace the original file (

rsim_tfdat.mat)andrunanrsim simulation with

this new data. This is done by typing

t=[0:.001:1];

u=sin(100*t.*t);

tu=[t;u];

save newfrom.mat tu;

!rsimtfdemo -f rsim_tfdata.mat=newfrom.mat

at the MATLAB prompt. Now you can load the data and plot the new results

by typing

load rsimtfdemo

plot(rt_yout)
