Subscript indices must either be real positive integers or logicals.

hi friends. i have this code . when i execute first or second part in seprate script , it works and gives me answer . but when i execute both of them in one script and after each other it shows me that error .

*Subscript indices must either be real positive integers or logicals.

what should i do?

PVbi = BAC .* PCBreakEven ;                                %part 1        
PVbiSum = [sum(PVbi(2:end,1:numel(duration)))];  



EV = BAC .* PC ;                                           % part2    
SigmaEV = [sum(EV(2:end,1:4)) ;sum(EV(2:end,5:8)) ;
           sum(EV(2:end,9:12)) ;sum(EV(2:end,13:16)) ;
           sum(EV(2:end,17:20)) ;sum(EV(2:end,21:24))];

What does it show?

whos BAC 
whos PCBreakEven 
whos EV
whos sum % !

BAC is double 37*1

PCBreakEven is double 37 * 6

EV is double 37*24

PVbiSum 1x6 double

SigmaEV 6x4 double

Hi,

I think, you migth get error in SigmaEV. Please check vaiable EV has 24 column. If not please check PC value.

when i execute SigmaEV first i get error in PVbiSum and when i execute PVbiSum first . iget error in SigmaEV

EV has 24 column . and pc is 37x24

Your code should work with the data you specified. Please upload all your variables in a mat file to see what is happening.
