Hi, I am having trouble in my code as I am trying to solve set of ODE`s and Exponential equations all 9 of them are dependent on each other and need to be solved simultaneously. Please someone see through it and help me. I am attaching my code.

Use a well tested ODE integrator of Matlab instead of a hard coded method without stepsize control.

In an assignment A(:) = B, the number of elements in A and B must be the same.
Error in Untitled (line 146) SOM(i+1) = SOM(i)+(s1+(2*s2)+(2*s3)+s4)*(h/6);

@KAPIL MAMTANI: You knew it, but the readers in the forum did not get this information before.

Your function handles for S and U and W involve the vector Y, so each place that it appears that you are calculating a scalar in the loop, s1, s2, and so on, you are calculating a vector; the one exception is t1. You can index that vector afterwards, but if you are going to be doing that you should be asking why you are calculating the entire vector: it probably indicates a logic error in your code.

@KAPIL MAMTANI: How could we know? All we see is your code, so we cannot compare it with what you intented to implement.
