Multiplying Functions

[ptc-4908634]

Dear experts,

I'm working since three evenings to solve a (what I think) quite simple problem, but I can't manage to solve it. Therefore please help me!

I try to multiply two functions that dependend on the same variable (phi_wind). I want to recieve the solution phi_wind = [r_W(0°)^2, r_W(30°)^2, ... r_W(330°)^2] but MathCAD calculates the scalarproduct instead. I tried everything (for loop,...), but I never get the solution I want to have.

The calculation describes the turbulence problem of a wind turbine.

Thank you for your help,

Muh

Much easier to help if you post your actual worksheet. Looks like you want to use the "vectorize" function.

Mathcad is right in calculating the dot product as rW(phi) is a vector. If you want the individual components be multiplied and forming a new vector you have to use "vectorize".

BTW, you have to click on "Erweiterten Editor verwenden" at the upper right corner of a new posting to be able to attach a worksheet.
