Matrix in mathcad

[ghass]

There is sth I miss abt matrix in Mathcad. I have 3 values of yyyd and I insert and compute the value of bb. Instead of computing individually, I put them in matrix and try to get the final answer in matrix. I try two times as shown in the green box but couldn't make it. Any help will be appreciated.

use the "vectorize" operator

I vectorized xx but still i have error?

you have to vectorize the equation, not just the variable(s).
