Hi,
Does anybody know if there is any command in matlab, to calculate the RMSE (Root Mean Square Error) in a curve fitting problem?
Thanks

One way is to compute it yourself. You just need to compute the root of the mean of the squared errors (hence the name):
y = <true values>
yhat = <fitted values>
RMSE = sqrt(mean((y - yhat).^2));

When I try this code I get a parse error at the first "<" in each line saying it's an invalid use of operator. How do I fix this?

Comment out these two lines:
y = <true values>
yhat = <fitted values>
Now add lines that initialize y to the actual values to be fit against, and which initialize yhat to be projected or modeled or reconstructed values that you want to compare to the true values.
