Can Matlab do Weighted Spearman Rank Correlation?

Very new to Matlab and looking for help. I am trying to calculate a weighted Spearman rank correlation. I am currently using the built in function in the statistics tool to calculate the normal spearman rank correlation:

[rho, pval] = corr(x, y,'type','spearman','rows','pairwise');

Where x is a matrix and y is a vector. I also have another vector W which is the weight of each observation row. Does anyone know of another function or script that incorporates the weight?

The formula would be: rho = 6 * SUM[Wi(xi-yi)]^2 / n(n^2 - 1)

Thanks!
