  • the easiest way to convert matrix to one row vector

    - by niko
    Hi, Does anyone know what is the best way to create one row matrix (vector) from M x N matrix by putting all rows, from 1 to M, of the original matrix into first row of new matrix the following way: A = [row1; row2, ..., rowM] B = [row1, row2, ..., rowM] Example: A = [1 1 0 0; 0 1 0 1] B = [1 1 0 0 0 1 0 1] I would be very thankful if anyone suggested any simple method or perhaps points out a function if it already exists that could generate matrix B from original matrix A.

Is there a way to do that? Apparently this obfuscator doesn't handle multiple assemblies. If that's an issue, which other .NET obfuscator- that handles multiple assemblies- would you recommend?
