System of Equations Functions
find(var1, var2, ...), minerr(var1, var2, ...)—Returns the values of var1, var2, ..., that satisfy the equations and inequalities in a solve block. If you are solving for n variables, the solve block must have n equations. Matrix notation is allowed, as is solving for matrix variables.
When there is only one unknown, the solution is a scalar. Otherwise the solution is a vector where the first element is var1, the second element is var2, and so on. If there are more than one unknown, the result is a vector of the solved variables. You cannot solve for a single element of a vector used in the solve block. PTC Mathcad adjusts all the unknown variables simultaneously to minimize the error.
Arguments
var1, var2,... are scalar or array variables found in the system of equations. Guess values for each variable must be defined above or within the body of the Solve Block. If solutions are expected to be complex, complex guess values must be used.
