How to apply function "strrep" to more than 32 substrings?

Hi there,
It would be my great pleasure if anyone could assist me with the following error, caused after I applied strrep to more than 32 substrings:

It shows me the following error:
Error using objective (line 2)
Error: File: building_model.m Line: 260 Column: 11
Nesting of {, [, and ( cannot exceed a depth of 32.

If you make x a string array with 96 or more elements, then the entire code can be replaced with
%{
newIDFFile = regexprep(readIDFFile, '@@P(\d+)@@', '${x{str2double($1)}}')
%}
For example,
x = "Here!"+(1:96);
readIDFFile = 'hello @@P3@@, how are you? @@P48@@ says hi!';
newIDFFile = regexprep(readIDFFile, '@@P(\d+)@@', '${x{str2double($1)}}')
newIDFFile = 'hello Here!3, how are you? Here!48 says hi!'

I meant variable R values. for instance, set WinS_Construct = R1WinConstruction, set WinS_Construct = R2WinConstruction, set WinS_Construct = R3WinConstruction, and set WinS_Construct = R4WinConstruction
As my x-values varries between 1 to 4
Here is the x.mat file
Thanks @Walter Roberson again!

I do not understand what you are asking. Your x.mat contains a newIDFFile variable that looks to have had the @@ properly replaced when I compare to readIDFFile. You do not have variables Obj1, Obj2 or similar in .mat and you do not have any R variable either. Your x values are not between 1 and 4, your x values are
>> x([1 48 72 end])
ans =
1×4 string array
Columns 1 through 3
"set WinS_Construct = R1WinConstruction" "set WinE_Construct = R1WinConstruction" "set WinW_Construct = R1WinConstruction"
Column 4
"set WinN_Construct = R1WinConstruction"
I do see that you have lb = ones(1,96) and ub = 4*ones(1,96), but what does that have to do with the price of bananas in Walla Walla, Washington?
It looks like you might be trying to work with EnergyPlus ? https://bigladdersoftware.com/epx/docs/8-3/auxiliary-programs/idfeditor.html

oh, never mind.. Actually the problem is that my code is more complex and I just showed a portion of that to you. I figured it out BTW.
Thanks,

newIDFFile = readIDFFile;
for k=1:length(x)
newIDFFile = strrep(newIDFFile, sprintf('@@P%d@@',k), x(k));
end

Hi again @Bruno Luong
Thank you so much again for your help. However, I'm not sure why my first 24 variables are not being replaced. Any idea? Thanks
P.S i also tried the following, but it didn't make any difference.
sprintf('@@P%u@@',k), x(k))
