The SVG stands for "scalable vector Graphic" and below are the example for SVG matrix.

The matrix looks like this:

a  c  e
b  d  f
0  0  1

There is only first 6 values can be specified, you only provide 6 values to the matrix transformation function. Here is an example:

transform="matrix(a,b,c,d,e,f)"

The other transformation functions can be expressed as matrices. Here are some examples:

Translate

1  0  tx
0  1  ty
0  0   1

matrix(1,0,0,1,tx,ty)

Rotate

cos(a)   -sin(a)  0
sin(a)    cos(a)  0
     0        0   1

matrix( cos(a), sin(a),-sin(a),cos(a),0,0 )

Note: the values for cos(a) and sin(a) have to be precomputed before being inserted into the matrix. The parameter a is the angle to rotate.

Scale

sx  0  0
 0 sy  0
 0  0  1

matrix(sx,0,0,sy,0,0)

A skew transformation along the x-axis can be written as: Skew

1  tan(a)  0
0       1  0
0       0  1

matrix(1,0,tan(a),1,0,0)

The tan(a) value has to be precomputed before being inserted into the matrix() function.

A skew transformation along the y-axis can be written as:

Skew

1       0  0
tan(a)  1  0
0       0  1

matrix(1,tan(a),0,1,0,0)

Here is the output:
