Substituting Matrix into an equation with Matrix (Pile Interaction)

[ptc-5086232]

Good Morning Community,

Attached is a working copy the community was helping to resolve on previous post. In the attached file, I'm trying to substutite a matrix S_sub_p into an equation lamda, that yield a matrix and then subtitute lamda into alpha_sub_V to generate pile interaction. Previously I posted the PDF copy of the example was working on. Please help me to see what I'm doing wrong.

Regards,

Boyer

To take the log of a matrix you have to explicitly vectorize everything in the parentheses. However D*Sp has zeros on the diagonal, so then you get a divide by zero error. You will have to figure out what to do about that.

Does turning Gamma into a function of S.p solve your problem?

Thanks you so very much Werner. I tried that approach, but my work sheet was yielding an error message. Thanks again.

but my work sheet was yielding an error message.

Maybe because of your redefinition of Gamme as a matrix. Notice that I have deactivated this region.

Or do you mean that the sheet I posted throws an error for you?
