### Description

Name: | gen_diag_fit_full
Title: | Diagonal matrix generation full matrix fit
Author: | Wright Dose Ltd
Abstract: |

One compartment model with absorption compartment and CL/V parametrisation.
This script uses a diagonal covariance matrix to generate the data and a full covariance matrix to fit.

Keywords: | dep_one_cmp_cl; one compartment model; diagonal matrix; full matrix
