Need help to create matlab script to convert currency

Dear all,

I need help to write a matlab script to convert and calculate for the currency below. I can't figure out how to write it. Thanks so much in advance!

Convert from SGD to USD GBP EURO from SGD 1 to 25

Answer 1

Here is function for it : you can easily convert to a script if you want.

function currencyTable = convertCurrency(toUsd, toGBP, toEuro)  
  SGD = (1:25)';
  USD = SGD.*toUsd;
  GBP = SGD.*toGBP;
  EURO = SGD.*toEuro;  
  currencyTable = table(SGD, USD, GBP, EURO);
  % disp(currencyTable);  
end

Then call it from the command prompt or another script:

>> currencyTable = convertCurrency(0.74, 0.48, 0.68)

Nobel Mondal thank you for your reply. but the display have to be like below image and the result have to be from 1SGD to 25 SGD to equivalent to the rest of the currency.

[Nobel Mondal]

Well, on my end it looks the same which you have mentioned. Can you please show me the output you're getting?

[Walter Roberson]

If you are expecting the results to come out in blue, then you are going to have a difficult time.

If you are not expecting the result to come out in blue, then their solution looks pretty good; it comes out like

    SGD     USD      GBP     EURO 
    ___    _____    _____    _____

     1      0.74     0.48     0.68
     2      1.48     0.96     1.36
     3      2.22     1.44     2.04
     4      2.96     1.92     2.72

     6      4.44     2.88     4.08
     7      5.18     3.36     4.76
     8      5.92     3.84     5.44
     9      6.66     4.32     6.12
    10       7.4      4.8      6.8

Hi Nobel, Thank you for your help! below is the error i am facing.

Undefined function or variable 'toUsd'

[Walter Roberson]

You are attempting to run the code by using the menu Run function, or pressing F5. You cannot do that for functions. Instead you need to follow what he said,

Then call it from the command prompt or another script:

>> currencyTable = convertCurrency(0.74, 0.48, 0.68)

[Nobel Mondal]

If you're still facing the problem, just use this script ( in stead of the function)

    toUsd = 0.74; toGBP = 0.48; toEuro 0.68;
    SGD = (1:25)';
    USD = SGD.*toUsd;
    GBP = SGD.*toGBP;
    EURO = SGD.*toEuro;  
    currencyTable = table(SGD, USD, GBP, EURO);
    disp(currencyTable)

[KSK]

still can't. it still giving me the below error.

>> currency conversion(toUsd, toGBP, toEuro)
Undefined function 'currency' for input arguments of type 'char'.

[Walter Roberson]

You cannot name a function with a space. Your .m file name must not have any spaces in it. The first character must be a letter, and the characters after that must be a letter, or a digit, or the underscore ('_'). The permitted letters are ones of the English (Latin) alphabet, uppercase or lowercase.

[Stephen23]

Permitted function names are explained here:

thanks walter, now i am getting the error below. i don't why i can't display out the table like you show on the above.

 Error in currency1 (line 6)
    currencyTable = table(SGD, USD, GBP, EURO);

[Walter Roberson]

You do not show us what the error is. Is it possibly saying that there is no such function or variable "table" ?

[Nobel Mondal]

If you're using older than R2013b version of Matlab, it might not support table datatype.

[KSK]

Sorry guys i am using the version R2013a. Below is the error after i click run from the script.
