In MATLAB, what does ./ mean?
Also, I would like to take the derivative of an experimental plot. How do I do so?

x = [ 1 : 10 ]
y = [ 1 : 0.5 : 5 ]
x ./ y
x = [ 0 : 0.1 : 10 ]
y = x .* x
plot( x , y )
The "./" notation in MATLAB is used to denote element-wise operations on arrays. It allows you to perform operations on each element of an array individually, rather than on the entire array at once.
The "/" operator in MATLAB performs matrix division, while "./" performs element-wise division. This means that "/" divides the entire matrix by a single value, while "./" divides each element of the matrix by a corresponding value.
Yes, "./" can be used with matrices of different sizes as long as the dimensions are compatible. In this case, MATLAB will automatically perform implicit expansion to match the dimensions before performing the element-wise operation.
Yes, "./" is a MATLAB-specific notation and is not used in other programming languages. However, some other languages may have similar element-wise operations, such as Python's "numpy.divide" function.
To use "./" in your MATLAB code, simply include it between two arrays or a scalar and an array. For example, to perform element-wise multiplication on two arrays, you would use the notation "array1 ./ array2".
