Undefined function or variable

Hi All,

Can you please help me with this error, I'm trying to run DGSE model with code from paper's authors but it does't work . Attached the code.

IMP_NCC_pi

Undefined function or variable 'E'.

Error in IMP_NCC_pi (line 16)

X_v(2,1) = E(2,:)*X_v(:,1);

The error message clearly states that the variable 'E' does not exist. You need to check why you are using variable E here and how you can define its value.
