I have this matrix
val(:,:,1) =
0.5000 0
0.5000 0.3333
0.5000 0.6667
0.5000 1.0000
val(:,:,2) =
0.5000 0
0.1667 0.3333
0.5000 0.6667
0.5000 1.0000
val(:,:,3) =
0.5000 0
0.8333 0.3333
0 0.6667
0 0
I want to convert it from the 3D matrix 4x2x3 to a 12x2 matrix but that it is sorted as it was at the start.
So the output is this:
0.5000 0
0.5000 0.3333
0.5000 0.6667
0.5000 1.0000
0.5000 0
0.1667 0.3333
0.5000 0.6667
0.5000 1.0000
0.5000 0
0.8333 0.3333
0 0.6667
0 0
I think i have to use the reshape with permute function but i didnt quite get the correct syntax to ordinate properly the output.
Any help would be greatly appreciated.

The bulk of the work is done for you in this FEX download,

output = blkColon(val,[4,2])
