Hi All,
I am just wondering why is it so difficult to convert a cell array to matrix?
I used cellfunc on cell array of 59000 cells which took 7 seconds
but the conversion to a matrix of size
443320 , 7
took about 1080 seconds on my machine.
The cell2mat on the same data took appx 150 times more time.
I am just shocked. Should I replace the original cell2mat with a C routine?
