To find the first derivative of a function in Matlab, you can use the "gradient" function. This function takes in a vector of values representing the independent variable of the function, and a vector of values representing the dependent variable of the function, and returns the first derivative as a vector.
Here is an example:
main.m284 chars16 lines
In this example, we define a function with x
values ranging from 0 to 2π, and y
values equal to the sine of x
. We then use the gradient function to find the first derivative of the function with respect to x
. Finally, we plot both the original function and its first derivative using the "subplot" function within a "figure" block.
Note that the "gradient" function can also be used to compute gradients of multi-dimensional arrays.
