creating four arrays from two cell arrays?

Hello there,

I have table (79*13). I have 1st column have values from 1-79 named gates and 12th column have mixed values (positive and negative).

I need to plot x = all positive values and corresponding gates in Y axis, similar for all negative values in x-axis and corresponding gate number at Y-axis.

i have extracted positive and negative using sort command.(image attached)

but i don't know how to extract corresponding gate number into array to do plotting?

A = gooddiff;
B = gatenumber;

Now Logical Indexing

pos = A<0;
neg = A>=0;
A_pos = A(pos);
A_neg = A(neg);
B_pos = B(pos);
B_neg = B(neg);

Now you can plot them

for sorting

[A_pos,inda] = sort(A_pos);
 B_pos=B_pos(inda);
 [A_neg,indb] = sort(A_neg);
 B_neg=B_neg(indb);

hey Thank you so much. It is working perfectly just 'pos' is 'neg' and the alter. Thanks again :)
