Hello
Im trying to run below function but constantly getting error
Attempt to grow array along ambiguous dimension.
Error in discrete2softmax (line 5)
s_m([1:sNum] + (inp'-1)*sNum) = 1;%problem
I know its caused becouse target is larger then array but please help how i should change my code to make it work
function s_m = discrete2softmax(inp,nmax)
% Convert discrete data into softmax
sNum = size(inp,1);
s_m = zeros(sNum,nmax);
s_m([1:sNum] + (inp'-1)*sNum) = 1;%problem
end

Did you intend to add data at locations outside the bounds of s_m? If so, you would have to do so with 2D subscript indexing, rather than with a 1D linear index, e.g.,
>> s_m=rand(2)
s_m =
0.7088 0.9239
0.1146 0.7881
>> s_m(3,4)=1
s_m =
0.7088 0.9239 0 0
0.1146 0.7881 0 0
0 0 0 1.0000
