Matrix And Vector Dot Product

Calculate array or vector dot product.

Enter arrays or vectors as a comma separated list. Do not put a comma at the end of the list. The two arrays must have the same number of elements. The dot product of two perpendicular vectors equals zero.

Tool Input

• rndtype : Rounding Type For Small Values

Tool Output

• Z : Dot Product

Calculate the matrix and vector cross product for a rectangular matrix from file data.

The cross product can be calculated from either the matrix or the transpose of the matrix. The number of elements in the vector must be equal to the number of matrix columns. The number of elements in the solution is equal to the number of matrix rows. The number of matrix columns does not have to be equal to the number of matrix rows (the matrix can be either square or rectangular).

Save the matrix to a text file as tab or comma separated rows with each row on a new line (or copy and past cells from a spreadsheet). The vector can be defined either in the text file or on the calculation page. As an option, save the vector as a comma or tab separated list. Refer to the example text file in resources.

Tool Input

• rndtype : Rounding Type For Small Values
• matype : Matrix Operation Type
• M : Input Matrix

Tool Output

Calculate matrix and matrix cross product for two rectangular matrix from file data.

The matrix cross product can be calculated from either the matrix or the transpose of the matrix. The number of columns in matrix A must be equal to the number of rows on matrix B. The resulting matrix has the same number of rows as matrix A, and the same number of columns as matrix B.

Save the matrix data to a text file as tab or comma separated rows with each row on a new line (or copy and past cells from a spreadsheet). Refer to the example text file in resources.
