Detailed Description

Stores a set of parameters controlling the way matrices are printed.

List of available parameters:

• precision number of digits for floating point values
• flags can be either Raw (default) or AlignCols which aligns all the columns
• coeffSeparator string printed between two coefficients of the same row
• rowSeparator string printed between two rows
• rowPrefix string printed at the beginning of each row
• rowSuffix string printed at the end of each row
• matPrefix string printed at the beginning of the matrix
• matSuffix string printed at the end of the matrix

Example:

std::string sep = "\n----------------------------------------\n";
Matrix3f m1;
m1 << 1.111111, 2, 3.33333, 4, 5, 6, 7, 8.888888, 9;

IOFormat CommaInitFmt(4, Raw, ", ", ", ", "", "", " << ", ";");
IOFormat CleanFmt(4, AlignCols, ", ", "\n", "[", "]");
IOFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]");
IOFormat HeavyFmt(4, AlignCols, ", ", ";\n", "[", "]", "[", "]");

std::cout << m1 << sep;
std::cout << m1.format(CommaInitFmt) << sep;
std::cout << m1.format(CleanFmt) << sep;
std::cout << m1.format(OctaveFmt) << sep;
std::cout << m1.format(HeavyFmt) << sep;

Output:

1.11    2 3.33
   4    5    6
   7 8.89    9
----------------------------------------
 << 1.111, 2, 3.333,  4, 5, 6,  7, 8.889, 9;
----------------------------------------
[1.111,     2, 3.333]
[    4,     5,     6]
[    7, 8.889,     9]
----------------------------------------
[1.111,     2, 3.333;
     4,     5,     6;
     7, 8.889,     9]
----------------------------------------
[[1.111,     2, 3.333];
 [    4,     5,     6];
 [    7, 8.889,     9]]
