Add several netcdf files of the same dimension

I/O API m3tools
1

Is there a tool in ioapi (m3tool) that can add multiple netcdf files of the same dimension?

nc1(four dimensions,6 variables)+nc2(four dimensions,6 variables)+nc3(four dimensions,6 variables)=nc4（four dimensions,6 variables(add same variables)）

Can the professor give me some hints? tks.

See https://cjcoats.github.io/ioapi/AA.html#tools, particularly
m3combo which does general linear combinations (of which sums are a special case), and m3diff which does 2-file sums and differences.

That worked， thanks for your response.
