How to copy a complex matrix in the workspace to an m-file?

I need to copy a large complex matrix from the workspace to be saved in m-file as a matrix (notice the complex sign (i or j or 1i) is not multiplied by (*). Part of the matrix is shown in the picture below.

Notice that I cannot use the code used for generating the matrix in the place (m-file) I work on for some complexity reason. Thanks in advance for your help

Why you want to save into m file? Instead save into a .mat file and load when ever you want in m file.

@Ismael: KSSV is right, the correct file format for storing data is a .mat file. .mat files are designed for storing data without loss of precision and class. .m files are for saving scripts and functions, i.e. code. Why do you need to store numeric data in some text file that is intended for storing code?

Thanks KSSV, Stephen. That is right, I thought about it, but I want to use it in a "Matlab Function" block in Simulink which I wasn't able to use it in the second file called by the main Matlab Function block. Another reason, I want to document the complex matrix (68x68) as an appendix.

Is it possible to save it in an excel file? Again the matrix is complex.

Thanks Adam, unfortunately, it only saves the real part of the complex matrix. I just tried it.

Does Excel itself even support complex data? You can separate it into real and imaginary parts and save those to their own columns.

[KSSV]

A = rand(5) ; 
B = rand(5) ;
C = A+1i*B ;

C_str = num2str(C);
C_cell = cellstr(C_str);

xlswrite('test.xlsx',C_cell)

Thank you so much KSSV, it works with some changes in the excel file after being saved. Appreciate it. Thanks also go to Adam and Stephen.
