How to solve and plot Differential equations in Matlab code

WebApr 12, 2024 · I have an issue in my code i.e.,"TIME LOOP NOT WORKING PROPERLY". I'm dealing with unsteady case. For that unsteady case the equation has dt (time step). in addition, I'm using COLD for previous time level(C^k) and CNEW for new time step level(C^k+1). here how can i include time level in my equation and reach steady state? Webequation to give us x and y, we'll define the function with function dxy = diffxy(t, xy) This function is called diffxy. called diffxy.m It takes a vector xy (which has all three of the variables we said we had to give matlab to define our differential equation in it) and a time vector, and gives us the dr brezina augusta ga
