I created a 3 by 3 matrix using the create matrix. I then created a second matrix b which is the matrix to the second power using the following:
b = MatrixPower[a,2] // MatrixForm
So I got a matrix in matrix form. But later on, I decided to change the matrix a and redid b except this time I got the following output:
MatrixPower[(my matrix), 2].
In other words, Mathematica did not carry out the command.
I restarted Mathematica and it still wont carry out MatrixPower.
I also did Inverse and it outputted :
Why is Mathematica not carrying out the calculations?
attached is the notebook
