What is Numpy correlate?
numpy.correlate() function defines the cross-correlation of two 1-dimensional sequences. This function computes the correlation as generally defined in signal processing texts: c_av[k] = sum_n a[n+k] * conj(v[n])
What does Numpy correlate return?
numpy. correlate simply returns the cross-correlation of two vectors. if you need to understand cross-correlation, then start with http://en.wikipedia.org/wiki/Cross-correlation. This will return a comb/shah function with a maximum when both data sets are overlapping.
How do you find the correlation in Numpy?
Example: NumPy Correlation Calculation
arange() to create an array x of integers between 10 (inclusive) and 20 (exclusive). Then you use np. array() to create a second array y containing arbitrary integers. The values on the main diagonal of the correlation matrix (upper left and lower right) are equal to 1.
