WebThe keys to handling empty matrices in a unified way are: empty indexing (that is, indexing with [] ); the fact that summing along an empty dimension gives zeros. Let r and c be the (possibly zero) numbers of rows and columns of m. m (:, []) is an r × 0 empty vector. This holds even if r or c are zero. WebFeb 3, 2011 · When finding values in multidimensional (i.e. greater than 2-D) arrays using the function FIND, it is best to get a single linear index from FIND then convert it to subscripts using the function IND2SUB.

Column space basis orthogonal representations are obtained in MATLAB using either null or orth. In fact, they work regardless of whether the matrices are symbolic or floating point. Since A has rank 3, the null space will have dimensioon 1. orth (A) spans the column space, which must have dimension 3. color change in latex
