How do I change the name of a variable (actually value of a character array) inside a loop?

Hello.

I have the following code:

for count_slot= 1:1:Np
    number = count_slot;
    .......
        mi_addpointprop('Current',0,Ip_theta_real);
    mi_selectgroup(count_slot);
    mi_setnodeprop('Current',count_slot);
    mi_clearselected;
    -------------------------------------------------

I want ,for every loop that takes place, to change the name of "Current" to " Current + the number of the loop". I am unable to find any information on this.

Thank you very much for any guidance!

Hi Matt,

Thank for the heads up. I understand why it is not a good idea, but the toolbox I am using is limited. I can not implement those sugestions.

mi_setnodeprop('Current',count_slot);

This is the only line I can edit. The first value, "Current" is the name I want to edit, the second is the group number, a concept specific to the toolbox used to create an interface with a different software.

I do not see any oher solution then to edit the name while in the loop. If you have any idea, it would be amazing.

Again, thank you for your time.

"I understand why it is not a good idea"

What you described is a perfectly good idea, and is very commonly done.

It is just that in MATLAB the term "variable" has a totally different meaning to how you used it.

"I do not see any oher solution then to edit the name while in the loop."

What you are asking is just to change some text. This is completely unrelated to changing the name of a variable.

for k = 1:5
    T = sprintf('Current%d',k) % character vector
end

T = 'Current1'

T = 'Current2'

T = 'Current3'

T = 'Current4'

T = 'Current5'

for k = 1:5
    T = "Current"+k % string scalar
end

T = "Current1"

T = "Current2"

T = "Current3"

T = "Current4"

T = "Current5"

Hi,

Yes it seems I lack some sleep. Thank you very much!
