Hi,

I have a matrix of 48000 rows by 1700 columns (everything is rowMajor)

when I do MYMATRIX.transposeInPlace() it crashes.

Why could this happen ? is this because its too big ?

Best,
Mehrdad

I forgot to mention that I used the latest development branch under windows 32 bit, and this function has worked ok for smaller matrices.

I recommend that you compile with exceptions enabled and put a try { ... } catch around that. If the reason for your crash is that memory allocation failes, that way you'll be able to catch it.

that might likely be the case because currently for rectangular matrices transposeInplace is just a shortcut for m = m.transpose().eval() and so it creates a temporary, and in your case a very big one! Implementing a true inplace transpose for rectangular objects is doable but very tricky!
