I have defined a function to find the slope of a circular plate with a hole as a function of the radius. I want to find the minimum slope which occurs somewhere between the inside and outside radius. I can only use the max() function if the results are in a matrix. The defined function is not considered a matrix in Prime. I was going to use the WRITEPRN function (and read the values back in) but when I do that, only the last value is printed in the PRN file. Attached is the worksheet. Any ideas on what I'm doing wrong?
Thanks in advance.
Solved! Go to Solution.
I would suggest that you use the zero of the derivative to get the desired value. You can use a solve block with find or the "root" function:
The problem in your sheet was that r is defined as a range and not as a vector. That way theta(r) IS NOT a vector (but rather some kind of iteration.
