Mathcad matrix problem

Hi!

I'm a college student having problems with the creation of the matrix. The informational failure is "Found a similarity while evaluating this expression. You may be dividing by 0 or inverting a similar matrix."

Your value Q7 is 0. in hd(Q)  you have Q7^-0.5, which means 1/sqrt(Q7).

well, if Q7=0, its square root is 0, and you're dividing by 0.

 

Success!
Luc

 

P.S.

To locate such errors, select the expression with the red error, then from the menu, in the Calculation tab use the error tracing arrows

to backtrack to the origin.
