Dear Listers:
I am trying to do an element-by-element computation in mata but am not sure if it is possible. Given a matrix Z with elements z[I,j], what I would like to do is transform the elements of Z using scalars a and b to create a new matrix W as follows:
How might this be done using the element-by-element colon operator in mata, if it can be done?
