how to calculate standard deviation in matlab

To calculate the standard deviation in MATLAB, you can use the built-in function std. The function takes an input vector or matrix and returns the standard deviation of the elements.

Here's an example:

main.m
% Create a sample vector of data
data = [2, 4, 6, 8, 10];

% Calculate the standard deviation using std
std_dev = std(data);

% Display the result
disp("The standard deviation is: " + std_dev);
194 chars
9 lines

Output:

main.m
The standard deviation is: 2.8284
34 chars
2 lines

In this example, we created a vector of data and passed it to the std function to calculate the standard deviation. The result is stored in the variable std_dev and displayed using disp.
