I am trying a code where I have to simple make all the positive values to 1 and negative values to 0 in voltsadd_val matrix but whenever i run the program the syntax doesnt work prroperly. I dont know whats wrong ..
eg
volts_add =
Columns 1 through 11
10.2478 11.0875 8.3853 -11.0500 14.2229 15.0626 12.3604 -7.0749 10.2478 11.0875 8.3853
Columns 12 through 16
-11.0500 14.2229 15.0626 12.3604 -7.0749
voltsadd_val =
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

here's an example:
voltsadd_val = [1 5 3; -2 -5 5; 1 -5 3];
voltsadd_val(voltsadd_val>0) = 1; % if pos, 1
voltsadd_val(voltsadd_val<0) = 0; % if neg, 0

Suspect the OP did the same thing not sure why the OP says it doesn’t work though. Maybe more expanation is needed then.
