coefficient	multivector source, blade blade	Copies the component of source, which is defined by the the blade blade, to the scalar component of the destination multivector

coefficient

Copies the component of source, which is defined by the blade blade, to the scalar component of the destination multivector.

Examples

m      = e1 + 2*e2 + 3*e1^e2;
?a1    = coefficient(m, e1);       // -> a1[0] = 1
?a2    = coefficient(m, e2);       // -> a2[0] = 2
?a3    = coefficient(m, e1^e2);    // -> a3[0] = 3
?arev3 = coefficient(m, e2^e1);    // -> arev3[0] = -3
?a4    = coefficient(m, e1^e3);    // -> a4[0] = 0
