Problem 44945. Calculate BMI

Quite challenging! Nice but you've got loads of things to improve je, je :d

We had a problem here. Check out your excersice asap pls.

%colnames = {'height' 'weight'};
%stable = array2table(hw,'VariableNames',colnames)
%stable = [0.01*2.5*stable.height,stable.weight/(2.2)]
%result= stable(:,2)/stable(:,1).^2
%bmi = result(:,5)

Can somebody explain why the assertain is failing in this approach?

The tolerance in assert is very high. Its not worthwhile to tune the decimal places to get that tolerance.
Reconsider the problem and reduce the tolerance.

This is the standard tolerance used in Cody. You'll encounter that frequently with many problems involving floating point numbers. There is nothing unsolvable/hard specifically about it.

interesting question

nice problem

Your first verification is FALSE

be careful about the unit convertion,
height = hw(:,1) * 2.54 / 100;

I made a good answer. and I was able to test hem in my desktop MATLAB but I got error with testing the first status here "error using assert"

Your function is returning the result as a row vector rather than a column vector. MATLAB defaults to writing results as a row vector when only one dimension is specifed, so change your for-loop assignments to bmi(i,1) = ... to force a column vector (or transpose bmi after the loop).

Please, do we need to sum up values of all rolls and columns respectively to calculate the BMI?

No. Use Elementwise operations.

Using regex just to wrap the entire code is just a tricky way of winning. The solution is no better than the others.

Did you use height in cm instead of in metres?

You have converted inches to centimeters and not meters by using the conversion factor 2.54.

Ah yes, thank you for pointing out guys, and sorry for the late response :/

"The condition input argument must be convertible to a scalar logical."
how this error is rectified?

Dividing height in inches by dividing by 39.37 fails. However, 39.3701 passes first test but fails the second. I had to find a closer value to satisfy second test, 39.37008. You should improve the test parameters.

bmi_correct and bmi_calculator are same. even then I am getting assertion error

What is wrong i this code, The final answers are also matching but it is showing as a fail, I am not getting it.

Leading solution is not correct. The code has comment to convert the height and weight seperately followed by the bmi computation. bmi should not be calculated in one line of code as in leading solution by crunching all the factors.

a very narrow range of assertions. The solution is correct, but can not proceed due to narrow limits of the assertions.

The problem specifies that the input hw is a matrix with two columns (not a table). So, the error is saying that you cannot use dot indexing on a matrix.

Didn't know this is how simple BMI is.

I've got the right values but I've failed the assertion somehow?

The expected output is a column vector containing ALL the bmi values, whereas your code returns a single bmi value i.e. the last one. Hope that helps!

increase the tolerance value..i had to be very specific to match the result

Nice!
