WebIf A is a vector, then sum(A) returns the sum of the elements.. If A is a matrix, then sum(A) returns a row vector containing the sum of each column.. If A is a multidimensional array, then sum(A) operates along the first array dimension whose size is greater than 1, treating the elements as vectors. The size of S in this dimension becomes 1 while the sizes of all … WebTo express a plane, you would use a basis (minimum number of vectors in a set required to fill the subspace) of two vectors. The two vectors would be linearly independent. So the span of the plane would be span (V1,V2). To express where it is in 3 dimensions, you would need a minimum, basis, of 3 independently linear vectors, span (V1,V2,V3).
