round down in matlab

To round down a numerical value in Matlab, you can use the floor function. The floor function returns the largest integer less than or equal to its input argument.

Here is an example:

main.m
x = 4.7;
y = floor(x); % y will be 4

3 lines

In this example, 4.7 is rounded down to 4 using the floor function.

You can apply the floor function to arrays as well. In this case, floor will round down each element of the array to the nearest integer.

main.m
X = [3.2, 5.8, 2.7, 6.1];
Y = floor(X); % Y will be [3, 5, 2, 6]
65 chars
3 lines

In this example, each element of the array X is rounded down to the nearest integer using the floor function.
