How can I solve dimension problem? Simulink

3 visualizzazioni (ultimi 30 giorni)
Hello everyone,
I am getting this error
" Error in port widths or dimensions. 'Output Port 1' of 'untitled/From29' is a one dimensional vector with 1369 elements."
saveV.mat size 1370x2 [time,Velocity]
saveACC.mat size 1370x2 [time,Acceleration]
both like,
0 3
1 5.9
2 4
. .
. .
. .
Also I do not know why size decreased from 1370 to 1369.
Thank you...

Sample Time is not number of samples! It is related to the rate at which the block is considered to output samples.

The Logical operands input of the If block must be a scalar signal. It's a block specification.
Also, the output of the If block should be connected to the Action Subsystem. It is also a block specification.

You need to transpose the data in the file. The first row is the time stamps and rows after that are samples for that time. You have two times and 1369 values.
This is unlike From Spreadsheet, which treats the first column as time if I recall correctly.
