Matrices and parameter of time Hi, Well, the solution to my problem maybe is easy, but i have really stuck with this. I have a process which evolves in three times, so there is the parameter of time (t=1,2,3).More particularly i have three 4*4 matrices, one for each time. In other words each element has three cordinates: time, row and column. The problems are these:i don't know how to express these matrices.Also i don't know how can i extract each element, for example, if i want the element from the matrix corresponding to the 3d time, the 2nd row, the 3d column, how will i extract this? I would appreciate any help and idea!Thank you!Anna S.
