// This is a routine to print a matrix using format suitable for pasting into
// the matlab IDE
//
// Templates:
// DerivedM e.g. derived from MatrixXd
// Input:
// input some matrix to be formatted
// name name of matrix
// Returns Formatted matrix
//
// Example:
// // M := [1 2 3;4 5 6];
// cout<<matlab_format(M)<<endl;
// // Prints:
// // [
// // 1 2 3
// // 4 5 6
// // ];
// cout<<matlab_format(M,"M")<<endl;
// // Prints:
// // M = [
// // 1 2 3
// // 4 5 6
// // ];

// Same but for sparse matrices. Print IJV format into an auxiliary variable
// and then print a call to sparse which will construct the sparse matrix
// Example:
// // S := [0 2 3;4 5 0];
// cout<<matlab_format(S,"S")<<endl;
// // Prints:
// // SIJV = [
// // 2 1 4
// // 1 2 2
// // 2 2 5
// // 1 3 3
// // ];
// // S = sparse(SIJV(:,1),SIJV(:,2),SIJV(:,3));
