finding a value from a point in a table
显示 更早的评论
I have a mat file with data like this, and I want to pull values that correspond to the blue numbers instead of the red numbers. For example, I am unable to find a value for (10,6).

Absolutely useless image -- attach some real data as text and show us the actual code used and then explain what it is you're after...if you have an array M, then
M(10,6)
is the value at that location...surely there must be more to the issue than that.

So you want to use your own indexing scheme to extract data from your array. It's possible, but is going to be a bit convoluted.
tbl = randi(10,[6,7]);
tbl(1,2:end) = 0:2:10;
tbl(:,1) = [0,0:2:8]
% use logical indexing to create and indes for where the row in the
% first column that is 6 and column in the first row that is 10
val = tbl(tbl(:,1)==6,tbl(1,:)==10)
