Code like I've used in the following console application will give you a display similar to what you might get if you were drawing the matrix on a piece of paper: using System; using System.Text; class Test { static void Main() { int imax = 3; // say int jmax = 4; // say double[,] mat = new double[imax, jmax]; // fill matrix with some arbitrary data for (int i = 0; i for (int j = 0; j mat[i,j] = ((i + 1) * (j + 1)) / 4.0; // build matrix string representation // field width of 5 and 2 decimal places assumed const char Vertical = '\u2502'; const char UpperLeftCorner = '\u250c'; const char UpperRightCorner = '\u2510'; const char LowerLeftCorner = '\u2514'; const char LowerRightCorner = '\u2518'; StringBuilder sb = new StringBuilder(); sb = sb.Append(UpperLeftCorner); sb = sb.Append(new string(' ', jmax * 7)); sb = sb.Append(UpperRightCorner); sb = sb.Append(Environment.NewLine); for (int i = 0; i { for (int j = 0; j { if (j==0) { sb = sb.Append(Vertical); sb = sb.Append(" "); } sb = sb.Append(String.Format("{0,5:F2}", mat[i,j])); if (j sb = sb.Append(", "); else { sb = sb.Append(" "); sb = sb.Append(Vertical); sb = sb.Append(Environment.NewLine); } } } sb = sb.Append(LowerLeftCorner); sb = sb.Append(new string(' ', jmax * 7)); sb = sb.Append(LowerRightCorner); string matrixString = sb.ToString(); Console.WriteLine(matrixString); } }
