Dear Prof,

I am aware that the code 'SVAR_restrict(&x, "C", 1, 2, 0)' is to inform Gretl of the nature of the restriction to estimate. I also know that this has to be repeated for several restrictions like in the model. However, I consider this to be rigorous especially when a large matrix is involved. Although, I know how a matrix can be created and used with the SVAR GUI, I don't know how it can be used with the SVAR_restrict(&x, ) function. 

Please, I need to be enlighten if this is possible or if I have to do the imputation for each restriction.

Thanks.
