How to sum 2 .mat file (Complex int)

hi,

I have 2 .mat file that their type is: comp int8

i want sum this 2 togheter (one by one array)

i used this:

 A=load('CDdata1.mat');
 B=load('CDdata2.mat');
 C=A+B

but it said:

Undefined operator '+' for input arguments of type 'struct'.

Error in Untitled (line 5)

C=A+B

The assignment of LOAD to a LHS variable creates a struct of the variable name provided with the fields the variable names in the .mat file. Hence, your variables are

A.CData1
B.CData2

where CData1/2 are the actual variables in the .mat files...you don't give us those.

C=A.CData1 + B.CData2;

is the syntax if variables are known and fixed. If there could be different variables inside the .mat files, use the dynamic field names options and/or structfun to write generic code--I just did another similar Answer here: https://www.mathworks.com/matlabcentral/answers/433003-average-and-plot-variable-from-multiple-mat-files#answer_349836 for how that can work.

ADDENDUM:

I just discovered for some unfathomable reason, "Complex integer arithmetic is not supported" -- How rude... :(

Besides the issue of duplicate variable names, you'll have to either cast to double to do the sum or as another poster noted, add the real and imaginary parts separately.

C=int8(double(A.data)+double(B.data));

if want/need the resultant to also be int8

Of course, you have to be aware of possible overflow altho it doesn't appear to be an issue with the specific dataset.
