How can i remove this logical operator error?

Operands to the || and && operators must be convertible to logical scalar values.

Error in parentProgram (line 2)
if((positive_sum<datestr('0,30','HH,MM')) && (negative_sum<datestr('1,00','HH,MM')))

Where am i going wrong?

One of the terms is not convertible to a logical scalar. Most likely, one or both of these terms are arrays. What does

size(positive_sum<datestr('0,30','HH,MM')

give you? It should be 1x1 to be used in conjunction with &&.

May be the functions ALL or ANY can help you out:

if all((positive_sum<datestr('0,30','HH,MM')) && all (negative_sum<datestr('1,00','HH,MM')))
