How I define the variable B in a function [A, B] = ReadHyperc​ube(strcat​(pathname,​filename))​; ?

[filename, pathname, indx] = uigetfile( ...
{'*.hdr','Image Cube(*.bil)';
   '*.*',  'All Files (*.*)'},'Pick a file','file path'); 
if indx == 1
    [A, B] = ReadHypercube(strcat(pathname,filename));
elseif indx == 2

I will appreciate it. Thanks

That depends on the ReadHypercube function. If the top line is similar to the following line, it should do what you want.

function [A,B]=ReadHypercube(filename_and_path)

Is this a question about the design of a function ReadHypercube that you are writing? If so, then what outputs would make sense for such a function?

Hi Rik,

[A, B] = ReadHypercube(strcat(pathname,'.bil'));

This arises when I try to process cubical data set (hyperspectral).This function runs well but when I run another piece of code

%Copy wavelength data into array
hyperdata=zeros(size(B,1), 4);
hyperdata(:,1)=B;
hyperdata(:,2)=B;

This gives me an error

Undefined function or variable 'B'

That's why I am trying to define 'B' as out put

We have no idea what function you are trying to use/modify, so we can't help you. Based on the second block of code, I would guess that B is a columnar vector that contains the wavelengths of the hypercube, but we have no idea what your function does or how it would have to infer this vector.
