Good morning,

I need to multiply a series by an element of a matrix, For instance :

I've got a series named varY, a matrix myMat, and I want to create a new series varX which is the product of element 1 of myMat and varY.

series varX = myMat(1) * varY

The only way I can do that is if I assign myMat(1) to a scalar; scalar temp = myMat(1) and then series varX = temp * varY.

I wonder why I cannot multiply a series by an element of a matrix.

Thanks!

Works fine for me:

Code: Select all


create u 10
matrix(3,3) mymat
mymat = 5.5

series y = 2

series varx = mymat(1,1)*y

Hi,

You are right, it works perfectly.

My mistake. Since I had created a matrix with only one column, I thought I did not need to specify the column in the expression series varX = myMat(1) * varY

So, the right way is to write series varX = myMat(1,1) * varY

Thanks a lot for helping me.
