Vectorization makes evry T calculation. But nor sure what you want to do.
Actually QSL is evaluating and also plotting. The blue trace simply looks like its the x-axis because of a scaling problem.
Both QVL and QSL start in the hundreds of Watt, but QVL goes up to 4,8 * 10^8 W, while QSL just up to 2.2*10^5.
If you need both in the same plot you may limit the y-axis to something like 10^5
or you multiply the QSL values by, let's say, 10^3 which is the same as showing them in mW instead of W (which is what ttokoro had done 🙂 )
As ttokoro already had shown, what you are looking for is called "vectorization" in Mathcad and Prime.>
Vectorization is applied if you want a scalar calculation to be done with vectors element-wise. All involved vectors must have the same size and vectorization does not work recursively.
Prime applies vectorization automatically if the operation is not defined for vectors. So when v is a vector (in Prime only column vectors are considered vectors), Prime applies implicit vectorization if you type v2 but uses the scalar vector product when you use v*v.
Exponentiation (and likewise division) is not defined for vectors, so instead of issuing an error message, Prime automatically applies vectorization. While this is a convenient approach, it also means that, as in the example below for a*a/b, one might initially assume that the calculation is being performed element by element and continue to compute with incorrect results.
