what is the maximum number of nonlinear equations that can be solved in Mathcad with the Find function?
I am at 50 and it will not let me enter in the 51st variable.
Solved! Go to Solution.
From the Mathcad 15 help file:
It is more likely a limit on the number of arguments in the function call. Try combining the variables into a vector (so instead, of x and y, x[0 and x[1, and solve for x)
Thanks, that fixed it to put some of the variables into one of the arguments as a vector. I put a 7 row by 1 column vector in the 48th argument. It solves correctly, but now I need help on how to access these values in the 48th argument.
F(P1,P2,P3):=Find(x1,x2,x3,x4,x5,....x46,x47,x48) where x48 is a 7 row by 1 column vector with succeeding rows of x48,0 x48,1 x48,2...
I access it as follows
where each x1, x2, x3 has a numerical value.
I'm wondering how to get at x48? If I say F(P1,P2,P3)sub48,0 it shows the 7x1 vector. If I subscript a 1 for the 0 it shows up as red. How can I access each individual part?
So, I have a huge 'find' equation where combining variables into vectors would be advantageous. Following your advice, I can replace everything with subscripted variables. Nice, but that makes the equations awfully hard to read since everything becomes x[0, x[1 instead of Pressure, temperature or whatever. Here's what I got to work based on your advice.
My question is if there is anyway to stick with the native variables in the equations? Something like this is what I'm after, but never seems to work (no solution found).
Thanks, (3.1 attached)
