Hello,
I have two curves, one corresponding to a real function and the second is its estimated curve.
The whole simulation takes palce in simulink. How can I compute the absolute error between the two curves?
I have attached the figure for your consideration

Absolute error is the difference of values of signals at the given simulation period.
absolute_error = abs(signal1_value - signal2.value);
In order to achieve this in simulink just add subtraction block between two output signal and resultant output is passed through the Abs block.
As an example, refer to the following model
