Hello!

I'm having trouble using the maximize function for 4 variables that I need to optimize. I'm using Solve Block, all the variables are defined and even then it hasn't worked.

I'm sending the file in case someone can please help me.

Thank you!

Prime is right when it moans about a unit mismatch. You forgot to add units for the constants in the last few inequations.

Furthermore you have typed square brackets twice. This creates a matrix. Use parentheses only to structure your expressions.

Re: Maximize 4 variables MathCAD 6 Prime

Hi,

I get a different lower answer for Wp.

You define some angles at the start of the sheet. I have changed them to include the unit degree.. I have changed all the instances of the unit deg by deleting them in the solve block.

Cheers

Terry

Can't say why. Maybe you missed to delete a "deg" when you cleaned up the worksheet?
