What part of it does he need to see? Your file includes struct and includes cell array of struct, and includes some arrays with several thousand entries. You would have to transfer in a way that your friend could read.
For example, you might be able to use jsonencode() on a modified version of the data. Not an exact version, because your data includes complex numbers, which json does not support; you would have to either convert those to string or convert to real() and imag() lists. Also, your radius is a 1 x 10 cell array, each element of which is a scalar double, and jsonencode converts that as-if it were a plain 1 x 10 vector of double.
Does your friend have to know the exact details of the data, or are only some variables needed, or would it be acceptable to do things like split into real and imaginary components?
