Using the From File data

Hi,
I'm using the 'From File' block to import data from a .mat file to Simulink. My problem is that I don't know how to select the data from my .mat file.
My file has 2 rows, the first one represents a time vector and the other represents my data. How can I select each row of the .mat file form the output of the 'Form File' block, so that I can work with each row as an individual vector?
Thanks in advance.
Best regards, Ana

You can't. Simulink is time-based, so it will use the data stored in your MAT file to output at each time step the relevant value of the signal. Since you only have one signal in your MAT file, the output of the block will be the value of that signal at each time step. Have a look at the documentation for more details.
HTH,
Arnaud

The first element of each column contains a time stamp. The remainder of the column contains data for the corresponding output values.
First row is the time and each of the other rows represents one output, each row can be considered a vector.
data=[t1 t2 t3...;u1 u2 u3...;v1 v2 v3...]
