Pl =[ 0.02
0
0.06
0.04
0
0.35
0.03
0.15
0.13
0.02
0.2
0.01
0.02]
Pl is one of the variable, now i want to add all the elements of Pl
so i did sum(Pl) <<< well known syntax to add elements of an array
>> sum(Pl)
now below is the error it was showing
Subscript indices must either be real positive integers or logicals. can any one plz let me know... and one more thing after completion of program if i put cursor on any variable it is showing that variable values/array/matrix like how we normally see while debugging

You might have another function called sum in your current directory and shadowing the built-in function sum. Please check it.
