from File and if block conditions error

1 view (last 30 days)
Hello everyone,
I am building a Simulink structure for my homework which is about EVs.
I have Drive_cycle.mat contains time and corresponding speeds. It is directly connected (used goto, from blocks) to if block.
But I am getting an error. And I could not solve it.
I really appreciate any help you can provide. Thank you

Hi Hasan, If possible could you please share the model and drive cycle data here. I think that you are giving the drive cycle as input to the 'if' block. As drive cycle has 2 columns , 'if' block is not able to know with whom to compare the given value. Also instead of goto and from block , first open the subsystem and try connecting the drive cycle directly to the if block.

CYC.mat size 1370x2 [time,Velocity]
0 3
1 5.9
2 4

If block specification. the output of the If block should be connected to the Action Subsystem.

This does not explain the error about the port dimensions, or why 1369 instead of 1370.
Real problem is that your data must be 2 x 1370 instead of 1370 x 2

Transpose your mat data. Timestamps are first row not first column.
