Hello,

SMath uses column matrix as a vector. Therefore:
mat(4,5,6,3,1)^2=77
mat(4,5,6,3,1)*mat(4,5,6,3,1)=77
4*4+5*5+6*6=77
represents scalar products of two vectors, resulting in scalar.
However, row matrix can not be used this way
mat(4,5,6,1,3)^2=#@#
It is regarded as matrix product of two matrices, resulting in matrix.
mat(4,5,6,1,3)*mat(4,5,6,1,3)=#@#
Of course, it is not possible - wrong numbers of rows/columns. You can do only this:
mat(4,5,6,1,3)*mat(4,5,6,3,1)=mat(77,1,1)
mat(4,5,6,3,1)*mat(4,5,6,1,3)=mat(16,20,24,20,25,30,24,30,36,3,3)

You are welcome,

If I understood you well, you need the element-wise matrix operations.
These operations need to be done with loops and specific matrix elements.
For instance:
A←5
B←4
C←mat(4,5,6,1,3)
for(i,range(1,length(C)),el(E2,1,i)←{(A-el(C,1,i))^2}/
E2=mat(0.25,0,0.25,1,3)

I hope this helped. If not, just be more specific please.

Regards,
Radovan
