I want to write a code in Matlab for the Backward Euler Method for 2x2 systems, using the fixed point iteration to find the yn+1.

y1n+1=y1n+h*f(tn+1,y1n+1,y2n+1) (1)

y2n+1=y2n+h*g(tn+1,y1n+1,y2n+1) (2)

Could you tell how I use the fixed point iteration??

At (1) the fixed point iteration will calculate y1n+1, y2n+1 will be calculated at (2) but it is already used in the equation (1) ...
