Could anyone help me with this problem?
I have to implicit functions, f(x,y), g(x,y) and want to obtain a matrix of solutions for their common zeros, in which the lines correspond to constant values of y, and the colums to constant values for x.
An equivalent question is: how do I get a matrix with gridpoints values for an implicit system of equations f(x,y)=g(x,y)=0.
I need large values for the dimension of matrix(say 1000), so I'm afraid solving 1000 a system of equation will be too time consuming.
Is there any way to store coordinates of a plot in a file automatically?
