delete last value of a vector in matlab

To delete the last value of a vector in Matlab, you can use the end keyword to specify the last element index, and the [] operator to delete it. For example:

main.m
% create a vector
v = [1 2 3 4 5];

% delete the last value
v(end) = [];

% display the result
disp(v); % output: [1 2 3 4]
124 chars
9 lines

In this example, the end keyword is used to get the last element index of the vector v, which is equivalent to 5 in this case. Then, the [] operator is used to delete the element at index 5 (i.e., the last value of v). Finally, the modified vector is displayed using the disp function.
