error from command window as the codes involves local functions

some one plz help me ,am getting problems in call functions to plot the gaph codes. here are codes

Please show us the full and exact text of the error message, all the text displayed in red in the Command Window (and if there are any warning messages displayed in orange, please show us those too.) The exact text may be useful and/or necessary to determine what's going on and how to avoid the warning and/or error.

I suspect you're copying and pasting this code into the Command Window, including the local function definitions. That's not going to work. If you're using a release that's less than (I think) ten years old, you can have script files containing local functions. Just write this code in a script file and run it by typing the script name.

The code gives no error message when executed here (see above).

Could you explain in more detail what you mean by "am getting problems in call functions to plot the gaph codes" ?

If you use a MATLAB release >= R2016b, save the complete code in a .m - file, load this file into the editor and click the "Run" button.

If you use a MATLAB release < 2016b, save the two functions in a .m - file with name "goalTimes.m" and the part of your code without the functions (the script part) as two separate files. Then load the script part into the editor and click the Run button.
