what are the components of Z = resizem(z1,scale). i need to interpolate my satellite data, so that it can be transformed into 2.81*2.81 size which is the ize of my CMIP5 model data

I have to increase the resolution of my satellite data which is 1*1.25 to my CMIP5 model data which is 2.81*2.81. I was using resize command in matlab, but not getting what inputs I need to feed in z = resizem(z1,scale). Cananyone please help me to inform what are these components in command?

According to the documentation for resizem, Z1 is your original data grid (A 2-dimensional matrix representation of your satellite data). The function returns a new Z which is "scale times the size of the input Z1".

Your intentions with the function and how you want to scale the data are vague.

For a 2-D matrix of size MxN, how does that relate to the 1*1.25 and the new data 2.81 by 2.81? What significance does the 2.81 have? If its merely size would that mean the new matrix size for scaling is M/1*2.81 by N/1.125*2.81?

We have no knowledge of how the 1 by 1.125 and 2.81 and 2.81 relate to the arrays. Does scaling a side from 1.25 to 2.81 imply a linear scaling of array elements corresponding to that side by a factor of 2.81/1.25?
