Using Bicubic Interpolation on unevenly spaced data.

Hey all, I want to use bicubic interpolation a dataset that is monotonic increasing and plaid but not evenly spaced. There is a Microsoft Excel function to do this, https://mathformeremortals.wordpress.com/2013/01/15/bicubic-interpolation-excel-worksheet-function/ but Matlab doesn't seem to have anyway to do this. Does anyone know how I can proceed from here, "Spline" interpolation isn't cutting it for me. Maybe I can convert the VBA excel code into matlab code? Is there a matlab function I'm not seeing?

Thanks
