hi everyone,
I need to plot a graph for system of nonlinear equations with multiple variables.
here is some example of system nonlinear
f1=3.65a^2-2ac-7ad+3.65b^2+7bc-2bd-1.65a+6.22b+0.5=0
f2=13.22a^2-7ac+2ad+13.22b^2-2bc-7bd-6.22a-1.65b+0.24=0
f3=2c^3-2ac-7bc+2d^2+7ad-2bd-0.2=0
f4=c^2+d^2-1=0
with initial condition (0.7, 0.2, 0.6, 0.3)t. I solved this using Newton's method and here the iteration
n a b c d error
-----------------------------------------------------------------------------
0 0.70000000 0.20000000 0.60000000 0.30000000

2 0.98731221 -0.03486513 1.01757054 -0.00041099 0.14723853
3 0.97161166 -0.04147173 1.00014326 -0.02109827 0.02068727
4 0.97133096 -0.04161789 0.99976714 -0.02158814 0.00048987
-----------------------------------------------------------------------------
I need to plot all the equations in one graph.
thanks to everyone who help me with this :)
