Indexing again

Hello To All,

 

A few of you were really helpful in pinning down my indexing problem. In the attached is part of what I have been working on in the background. Please do not get too hung up on what the overall picture is or anything until the end of the sheet, you will see that I have created a couple of tables toward the end of values and have integrated between two sets of values (column 1 of each table with matrix Z(I) to get some areas and then have integrated these areas to get a volume. I now want to do this in terms of j I.e. get 5 volumes to account for each column of the tables. Any ideas where I am going wrong?

 

Thanks,

 

Andy.

Re: Indexing again

You create a 2D array b, then try to address it as a single dimension vector:

If you do the interpolation against the whole column "cntrl-shift-c", things work better:

Re: Indexing again

Many Thanks Fred!

 

So as each is a column in the b matrix that makes allot of sense!

Re: Indexing again

Fred,

 

any idea where I am going wrong in the attached? I am now trying to do the same thing again but as a function. I think the problem is now the same (my lack of understanding of the dimensions of what I am doing). Any help welcomed.

 

Thanks,

 

Andy.

Re: Indexing again

You must have an integer for an array index phi = ??

Re: Indexing again

So everything to this point seems to be working but this specific operation is not happy?

Re: Indexing again

The function b(I,phi) does not create a vector, so the linterp in Area_b fails.  See attached

Re: Indexing again

Thanks Fred,

 

Out of interest, why does the linterp for Wl(x,i,Phi) work without a vector but not the Area linterp?

 

Thanks,

 

Andy.
