Why do I receive error "Index in position 2 exceeds array bounds"

Hi,

In MATLAB AppDesigner, I have written this code. Everything is fine except line CLTDRR = app.CLTDR (1,app.hr) where I am trying to get a specific number from an array app.CLTDR. app.hr is always less than or equal to 24 based on input but it still shows the error "Index in position 2 exceeds array bounds (must not exceed 24)". But app.hr is never greater than 24. Also, CLTDRR is a 1 row and 24 column vector.

Print out what app.hr is. It is likely a string and not a numerical value since you are reading it from the drop down widget. If it is really a string (or a char array), you can use

value = str2num(app.hr)

to convert it to a numeric value.
