WebIf given as inplace=false, or if this option is not included in the calling sequence, the result is returned in a new Matrix (or Vector). The condition inplace=true can be abbreviated to inplace . The inplace option must be used with caution since, if the operation fails, the original Matrix (or Vector) argument may be corrupted. WebC = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array.
