Hi, Got a little problem in 'FROM FILE' block in simulink.
In my system I've added 'FROM FILE' block which gets data from file and then performs calculation using 'MATLAB FUNC' block. When I tried to open '.mat' file (from which the 'FROM FILE' block extracts data) in MATLAB it imports as 2X20 array. But When I try to run in Simulink I get the following error:
"Error in port widths or dimensions. Output port 1 of 'xxx/From File' is a one dimensional vector with 1 elements."
Thanks in advance.

The data in the file needs to be a certain format (first row is treated as time samples, following rows as data). Make sure you conform to the one of the formats as described in the documentation.

I am also running into this error here. I tried both as suggested by Kaustubha: ie.
1, 2, 3, 4,
120, 121, 122, 123
where the first row is the time samples and the second row the data and also that matrix transposed. I have no luck either way. Seems like a simple thing to do but it has become a hassle to get past this error.
