How to write this formula in Matlab

Hello to everyone,

how can I traduce this formula in Matlab:

Ustat and Ucalib value are float number.

Thank you for your help.

Hi Nicolas Ostinelli,

You can refer to the code below.Let me know if there is any error.

%constant values

U_stat=0.12;

U_calib=0.3;

U_stat_sq=U_stat*U_stat;

U_calib_sq=U_calib*U_calib;

% calculating the summation part

sum=0;

n=10;

for i=1:n

sum=sum+U_stat_sq*i;

end

sum_sqrt=sqrt(sum);

first=(1/n)*sum_sqrt;

first=first*first;

U_fin=sqrt(first+U_calib_sq);

Ufin = sqrt((1 / n * sum(Ustat .^ 2))^2 + Ucalib .^ 2)

Answer 3

Hi,

It is my understanding that you possess Ustat (float number array) and Ucalib (float number) and you want to rewrite that formula as a representation in MATLAB. The following code illustrates how to achieve the above:

U_fin=(((1/n)*sum(Ustat.^2))^2+Ucalib.^2)^0.5

Here I have used ".^2" notation for element-wise squaring arithmetic operation, which saves me the effort of writing another for loop. Hope this helps.

I agree. I've posted this formula already. SQRT is faster than .^0.5 .
