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}] On 9 Jul, 2011, at 7:32 AM, yashar wrote: > hi > in mathematica > how i can produce a general n by n matrix so that each of its elements be a variable of t??? > how i can take derivative of this matrix with respect to variable t? > how i can with equating this n by n matrix with another n by n matrix which its elements are known obtain unknown elements of this general n by n matrix? >
