Hello Yashar,
Here is an example:
5x5 where each element is a function of t
fiveByfive = Array[matrixFuncs[#1, #2][t] &, {5, 5}]
The derivative of the matrix with respect to t
fiveByfive = Array[matrixFuncs[#1, #2][t] &, {5, 5}]
I am not sure what you are asking for with your third question, but perhaps this gives you a direction:
anotherfiveByfive = Array[otherFuncs[#1, #2][t] &, {5, 5}]
Table[fiveByfive[[i, j]] == anotherfiveByfive[[i, j]], {i, 5}, {j, 5}]
