Run with command line but not with simulink

Hi,

I have a function that works well in command line. I integrate it into a simulink and it's not working.

Errors are like :

• Mixed field types in structure arrays are not supported
• FIND requires variable sizing

Any recommendation ?

NB:I am using Matlab 2017b

What is the command that you are trying to use? Please include more information about your code.

Hi,

I have a funciton with several inputs that works. This function include a load of a .mat which is a structure file.

I added this function to a MATLAB function in simulink but first it gave these errors :

• Mixed field types in structure arrays are not supported : it came from the load of .mat ! ( i don't know why because for me, it's working when i run it alone) .
• FIND requires variable sizing : i found that when using the function (another one) in simulink, it's not accepting my code with the Find funciton. So, i made my changes and it's OK now.
• Finally, i tried to use the S-function inside the simulink instead of MATLAB function and i get the error of Not enough input arguments.

Thank you in advance but i really don't know why using the function into simulink is not working where it works alone ?!

What is a "structure file"? How do you "add a function"?

Maybe the problem gets clear, if you post a minimal working example, which reproduces the problem.

Sorry for this unclear question,

i attached an example.

the function 'test_test.m' works well but inside the test.slx it is not working.

the error is :

Any idea ??

I am just guessing based on the text of the error, but it seems that Simulink has a problem loading the file 'test1.mat' because there are different field types.

it also says "use the command 'whos -file test1,mat' to view the variables in the MAT file'

Did you do this? What is the result?

[Mohamad TOUT]

yes i tried this but i don’t have different types in ‘test1.mat’ !

the function ‘test_test‘ uses the file test1 without any problem but when using the same function ‘test_test‘ inside simulink, it gives the above error !

Please Help :)
