MathCad has several clever "vectorization-type" capabilities - but
there is one simple thing I can't find. Suppose
I have a 3 by 3 matrix A and I want to put in the second column some
other column vector V. how can I do that
in one fell swoop without having to write a silly loop? "Augment" and
"stack" don't help. It would be something like the submatrix function,
except that submatrix works only to extract a submatrix - not to write
into one. Using the same idea as submatrix
one could imagine a "submatrixin" function like
submatrixin(A, 1,3,2,2) = V that would put V in the second
col of A.
Could there be something like that in recent versions that I don't have
in MathCad2001i?
Many thanks
