define length n of a vector x in matlab

To define the length n of a vector x in MATLAB, the length function can be used. This function returns the number of elements in a given array, including the highest dimension.

Here's an example code snippet:

main.m
x = [1 2 3 4 5]; % define a vector
n = length(x);   % calculate its length
disp(n);         % display the result
113 chars
4 lines

Output:

main.m
5
2 chars
2 lines

In this example, x is a vector with 5 elements. The length function is used to calculate the length of x and store the result in the variable n. Finally, the disp function is used to display the value of n. The output shows that the length of x is 5.
