Dose any one know any wrong with this function?

Dose any one know any wrong with this function?

 function [nom]=intonom(int,conv)
   nom=((1+int)^(1/conv)-1)*conv;

I wanna to calculate the interest by using this calculation, but it always say wrong.

[Birdman]

What do you want to calculate? What do you give as input, scalar, vector? Be more specific and explain it with an example.

@a a: what size are int and conv ?

"but it always say wrong."

Please show us the complete error message. This means all of the red text.

PS: using int and conv as variable names, because these will shadow the inbuilt int and conv functions. Always use which to check if a name is already defined.

I give int(interest for year), and conv(how many years) as input

[a a]

do we have to define int and conv firstly? when i typing it, it shows, _ _ _ * function [nom]=intonom(int,conv) Error: Function definitions are not permitted in this contex*___

[a a]

@Stephen Cobeldick what i type are: function [nom]=intonom(int,conv) nom=((1+int)^(1/conv)-1)*conv; Error: Function definitions are not permitted in this context.

how can i fixed it?

You have to store that code in a file named intonom.m

Answer 1

[KL]

You have to store your code in an m-file under the same name as your function, in your case intonom.m. Once you do that, on the command line, you can type

 annual_interest = 0.125; 
 number_of_years = 8;
 result = intonom(annual_intereste,number_of_years)

and then result, according to your formula, is,

 result =

    0.1187

I get it, thank you every one!!
