I have Matlab 2014 and the function det doesn't work

I tried this:

>>D=[4 5;2 3]

D =

     4     5
     2     3

>>det(D)

Index exceeds matrix dimensions.

Why doesn't this work?

My guess is there is an issue with multiple dets on your path. Try

which det -all

Is the first hit what you expect?

Try this:

>> which -all det
built-in (C:\Program Files\MATLAB\R2014a\toolbox\matlab\matfun\@single\det)  % single method
built-in (C:\Program Files\MATLAB\R2014a\toolbox\matlab\matfun\@double\det)  % double method

Do you see exactly the same as I see? Or do you see the name of an m-file that you wrote ?
