MATLAB: Index exceeds the number of array elements (1) ERROR – not sure why.

errorindexMATLAB

I keep getting this error…but don't know why! It's a simple addition equation…for a series of vectors.

My code and excel data file are attached. Thank you for any and all help with this!!

>> WSBModel

Index exceeds the number of array elements (1).

Error in WSBModel (line 179)

Z1PumpTot(t)=S2(t)+S4(t)+S7(t)+S8(t)+S9(t)+S10(t)+S11(t)+S12(t)+S13(t)+S14(t)+…

If you break your script at line 179, you can clearly see the problem. S10 is only a 1x1 array and needs to be a 49x1 like all the other variables. Something is wrong with S10.

MATLAB: Index exceeds number of array elements (1)

We can't run your code because we don't have values of n, dt, A, and so on. But based on the information you provided, (T_night - T_out) produces a value that is not equal to 1 and your variable "A" only has 1 element.

Here's an example that reproduces the same error.

A = {42};
T_night = 10;
T_out = 2;
A(T_night-T_out)
% ERROR:  Index exceeds array bounds.

If that doesn't solve your problem, you could provide the values of "A" and "T_night - T_out" to get more help.
