The Body Mass Index, or BMI

Hi I tried to write a function called findbmi that would receive the weight and height as input arguments, and would return the BMI but for some reason it's not working. Please help

this is my code

Weight= input('Enter your weight in lbs, or typer 0 for SI units:')

if Weight==0;

Weight=input('Enter your weight in kg:')

Height=input('Enter your height in m:')

function BMI=findbmi(Weight,Height)

BMI= (Weight/(Height^2)) %kg/m^2

else

Height=input('Enter your height in ft:')

function BMI=findbmi(Weight,Height)

BMI=(Weight/(Height^2))*4.882427111

end

Just get rid of these lines:

function BMI=findbmi(Weight,Height)

[Dai Nguyen]

yeah but I have to use findbmi in my matlab T.T

[Dai Nguyen]

it's the requirement

[Dai Nguyen]

This is my new code

function bmi=findbmi(weight,height)

bmi= (weight/(height^2));

if nargin==0

weight=input('Enter your weight in kg:');

height=input('Enter your height in m:');

end

It showed an error "Function definition not supported in this context. Create functions in code"

file.

Was this the only code in your file? You should try to avoid mixing script files and functions.

@Dai: Create two separate files.

% findbmi_script.m
Weight= input('Enter your weight in lbs, or typer 0 for SI units:')
if Weight==0
    Weight=input('Enter your weight in kg:');
    Height=input('Enter your height in m:');
    BMI=findbmi(Weight,Height);
else
    Height=input('Enter your height in ft:');
    BMI=findbmi(Weight,Height)*4.882427111;
end

And a separate file with the BMI calculation:

% findbmi.m
function bmi=findbmi(weight,height)
bmi= (weight/(height^2));

Then run your script from the command line:

findbmi_script

[Dai Nguyen]

it said "Unrecognized function or variable 'findbmi_script'." for some reason

[Dai Nguyen]

oh nvm I got it

thank you
