Each gust of the clouded mood that seemed warmed by the heat of a heart flaming with anger has its counterpart in the chilly blasts that seem blown from a breast turned to ice with a sudden revulsion of feeling.
The dimension is the number of bases in the COLUMN SPACE of the matrix representing a linear function between two spaces. i.e. if you have a linear function mapping R3 --> R2 then the column space of the matrix representing this function will have dimension 2 and the nullity will be 1.
dimension. 1  a measurable extent, as length, width, or depth. 2  a hypothetical extension or continuum beyond these, in any of various physical or abstract systems: a theory involving higher dimensions. 3  measurements in length and width, and often depth.
