strange error with matrix largern then 2GB

[Daniel Heiserer]

I created a large matrix and then tried to multiply this matrix. This results in a dimension mismatch. There must be a bug.

Did anybody have the same experience?

 

My machine is x86_64 linux box with octave 2.9.3

 

best regards, daniel
