Method Details | [hide private]

### __init__(self) (Constructor) | source code
__init__(self, b2Vec3 c1, b2Vec3 c2, b2Vec3 c3) -> b2Mat33 Construct this matrix using columns. Returns: b2Mat33 Overrides: object.__init__

### __repr__(self) (Representation operator) | source code
Overrides: object.__repr__ (inherited documentation)

### __getstate__(self, additional_ignore=`[``]`) | source code
    Returns a dictionary representation of self, with
     dict(var=value [, ...])

    additional_ignore can be specified to ignore certain
    properties.

### SetZero(...) | source code
b2Mat33_SetZero(b2Mat33 self) Set this matrix to all zeros.

### Solve33(...) | source code
b2Mat33_Solve33(b2Mat33 self, b2Vec3 b) -> b2Vec3 Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases. Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases.

### Solve22(...) | source code
b2Mat33_Solve22(b2Mat33 self, b2Vec2 b) -> b2Vec2 Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases. Solve only the upper 2-by-2 matrix equation. Solve A * x = b, where b is a column vector. This is more efficient than computing the inverse in one-shot cases.
