how i can correct my program

Dear Sir/Madam

I attached two M-file to this letter. when I run the program with input data, like case 1, I can get resualt but when I put the third input data zero, like case 2, matlab give me the below message, please help me what am I doing? thank you

1)

MT=integral_thermalmoment_sub(0.006,0.002,0.002,25,30,1,0.3,35,40,300,1000,700,500,300,1,40,45)

MT =

-44177850149/14880348000

2)

Reza - you didn't attach any files to your question. Once you have chosen the file, you must press the Attach File button. Please edit your question and include these two files.

Given the error message and that the third input is changed to a zero, then your code must be trying to divide by this _power input. You may have to add a check in your code to prevent the division by zero from occurring. Or ask yourself if it makes sense to pass in a zero?

I already run these programs with matlab version 12a and I didn,t have any problem, but now with use matlab 14a , I have this message from matlab.

Did you see Geoff's remark about attaching the files. Make it EASY for people to help you by giving them something to work with.
