All matlab function gives output as class double.
e.g.
[I,J] = ind2sub([H W],idx);
it is clear that I & J will be integer type but then also matlab gives values of I & J as class double.
How can get output as class interger 'int16'?

Well, they could be done as uint64.
It would not be unreasonable for MATLAB to support passing in the name of the output type for ind2sub, but it does not currently do so.

function [I,J]=myind2sub(sz,idx)
I= mod(idx,int16(sz(1)));
J= int16( ceil(idx/sz(2)) );
end

@JAI PRAKASH: then copy ind2sub to your working directories, rename it myind2sub, and make whatever changes you want to the code. Do NOT change the original file.

Yes, if you change the built-in ind2sub, you jeopardize the functionality of other Matlab built-ins that rely on its normal behavior.
