How to fix this error please?

Error using eye

Requested 57660x57660 (24.8GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and cause

MATLAB to become unresponsive. See array size limit or preference panel for more information.

Error in Ex11_Bayes_AVO_Inversion (line 79)

Sigma_e = var_e*eye(nt*ntheta); % White noise covariance

[Walter Roberson]

What is the value of nt*ntheta?

Perhaps speye() would make more sense.

[Nisar Ahmed]

ntheta is 30 or 31 here

[Walter Roberson]

okay but we don't know nt

We also don't know how nt or ntheta are calculated in order for us to assess if the values are necessarily that high

[Nisar Ahmed]

Here nt is 1922.

nt is 1922 for each ntheta (1 to 30). how this issue can be resolved?

Hi @Nisar Ahmed,

I observer that you are trying to create a 59582x 59582 matrix in your script. You are getting the error due the maximum array size limitations in MATLAB. You can remove the limitations for the maximum array size by unchecking the maximum array size limit checkbox from the preference panel following this path.

MATLAB >Preferences > Workspace > MATLAB array size limit.
