how to calculate the arctangent of an angle in matlab

To calculate the arctangent of an angle in MATLAB, you can use the atan() function. This function takes one input argument, which is the ratio of the opposite to adjacent sides of a right triangle (also known as the tangent of the angle), and returns the value of the angle in radians.

Here's an example of how you can use atan() to calculate the arctangent of 0.5:

main.m
angle = atan(0.5)

This will return the value of angle in radians, which is approximately 0.4636.

Note that the input to atan() must be a numeric value. If you pass in an array or matrix, atan() will operate element-wise and return a corresponding array or matrix of angles.
