How to solve Index in position 1 exceeds array bounds (must not exceed 1).

Hello,

When I am trying to run my code in matlab 2020a version I am getting this error. but when I am running the same code in matlab 2018b version, it runs normally. why am i getting this error and how can i solve this error. Please guide me.

With regards,

What code?

Its a complex code which I am using to call initialisation of simulink model. And sorry, I cannot post my code publicly.

The error seems obvious. You should stop your code on the line of the error and examine the varialbe you are indexing into. It appears that the variable is scalar and you are trying to index >1 which is not possible.

hello again,

I have gone through the code. the code crashes at line. here the p0_A_SOEC_INIT is a constant value and after simulation the p0_A_SOEC_INIT_out is calculated at every time step and the final value of the simulation is considered. In my case the p0_A_SOEC_INIT always remains constant through out the system. but It has to be a vector. if i run in old versions p0_A_SOEC_INIT_out is stored as a vector in the workspace. In 2020a version it is storing as a single scalar value.

p0_A_SOEC_INIT = p0_A_SOEC_INIT_out(n_IC_SOEC,:);

You could always store it as a vector in the size you need it.

p0_A_SOEC_INIT_out=p0_A_SOEC_INIT_out*ones(1,size_you_need);

I tried but it wont work with my model

Without seeing parts of your code, I don't think I can help you further.
