matlab monotonicity

Monotonicity refers to the property of a mathematical function where the function either increases or decreases in value as the input variables increase. In MATLAB, you can check the monotonicity of a function using the "ismonotonic" function. This function returns a logical value that indicates whether a given array is monotonic or not.

For example, consider the following code:

x = [1 2 3 4 5];
y = [1 3 5 7 9];

ismonotonic(x) % returns true
ismonotonic(y) % returns true

In this example, the arrays x and y are both monotonic, as they both increase in value as the input variables increase. The "ismonotonic" function returns true for both cases.

Note that the "ismonotonic" function also has optional input arguments that allow you to specify whether the array should be strictly monotonic (i.e., strictly increasing or decreasing) or not.
