coefficient of variation using for loops in matlab

Here's an example of how to calculate the coefficient of variation using for loops in MATLAB:

main.m
% create a sample dataset
data = [3, 5, 7, 8, 10];

% calculate the mean
mean_data = mean(data);

% calculate the standard deviation
std_dev_data = std(data);

% initialize the coefficient of variation variable
cv = 0;

% calculate the coefficient of variation using a for loop
for i = 1:length(data)
    cv = cv + ((data(i) - mean_data) / std_dev_data)^2;
end

cv = sqrt(cv / length(data) - 1);

% display the coefficient of variation
fprintf("The coefficient of variation is %f\n", cv);

In this code, we first create a sample dataset called data. We then calculate the mean and standard deviation of the dataset using the built-in mean and std functions in MATLAB. We then initialize a variable called cv to 0, which we will use to store the sum of the squared deviations from the mean.

We then use a for loop to iterate over each element in the data array. For each element, we calculate the squared deviation from the mean and add it to the cv variable. Finally, we divide this by the length of the dataset minus one, take the square root of the result, and display the coefficient of variation using the fprintf function.

Note that there are more efficient ways to calculate the coefficient of variation in MATLAB that do not involve for loops, but this example demonstrates how to use for loops to accomplish this task.
