Error: Index exceeds matrix dimensions while using bsxfun in matlab

Question

My code is :

A =[1 5 8; 3 4 7;9 10 11]
B = bsxfun(@rdivide,A,sum(A));

On running, I get an error : index exceeds matrix dimension

Please help.

Answer 1

You have (very likely) defined a variable called sum in your workspace. clear it, rename it, and you'll be fine.

A =[1 5 8; 3 4 7;9 10 11];
B = bsxfun(@rdivide,A,sum(A))
B =

   0.076923   0.263158   0.307692
   0.230769   0.210526   0.269231
   0.692308   0.526316   0.423077


sum = 5;   %% Oops!

B = bsxfun(@rdivide,A,sum(A))
Error: Index exceeds matrix dimensions
