Error in extrema2 (line 73)

im = unique([smaxcol(:,1);smincol(:,1)]); % Rows with column extrema

Error in bf_13BBstar (line 267)

[beammax,imax,beammin,imin] = extrema2(all_stacked_int);

This is the error that is comming while am running the code. Can anyone please help me to sort out the issue. My work is pending due to this error.

This error occurs when you try to extract more number of elements/ rows/ columns than present in the matrix.

Example:

A = rand(5) ;   % matrix of size 5x5 
A(1,:)   % first row, no error
A(5,:)   % last row no error
A(6,:)   % there is no 6th row , so error 

In your case also samething is happened. Check the dimensions of the matrix properly when you are trying to extract rows/ columns.
