Coordinate Vector - Basis Transformation Matrix

Basis Transformation Matrix

Let B and C be two different bases of a vector space V, and let us mark with the matrix which has columns consisting of the C representation of basis vectors b1, b2, ..., bn:

_{C}^{B} = \begin{bmatrix} \ _C & \cdots & _C \ \end{bmatrix}

This matrix is referred to as the basis transformation matrix from B to C, and can be used for transforming any vector v from a B representation to a C representation, according to the following theorem:

If E is the standard basis, the transformation from B to E can be represented with the following simplified notation:

where

Famous quotes containing the words basis and/or matrix:

    “It was the custom
    For his rage against chaos
    To abate on the way to church,
    In regulations of his spirit.
    How good life is, on the basis of propriety,
    To be followed by a platter of capon!”
    —Wallace Stevens (1879–1955)

    “As all historians know, the past is a great darkness, and filled with echoes. Voices may reach us from it; but what they say to us is imbued with the obscurity of the matrix out of which they come; and try as we may, we cannot always decipher them precisely in the clearer light of our day.”
    —Margaret Atwood (b. 1939)
