Maths Array And Vector

Calculate vector (array sum, average, root mean square (RMS), and dot product) and matrix operations (matrix inverse, transpose, determinant, Crout factorisation (LU factorisation), and cross product). Enter each matrix row as a comma separated list, with a new line for each row. For large matrices the rows will sometimes wrap around to the next line. If the lines wrap, you must still enter a new line (enter key) for each new row. Matrices should have an equal number of elements in each row.

Solve a set of linear equations using matrix and vector operations. The matrix must be square (equal number of rows and columns), and must have an equal number of elements in each row. The matrix rows must be independent, and well conditioned.

CALCULATOR : Array Or Vector Operations (Sum Average and Root Mean Square RMS - File Data - Modern Browser Required) [FREE] ±

Calculate array or vector operations: sum, average, root mean square (RMS), and product from file data.

Save the vector to a text file as a list with each item on a new line (or copy and past cells from a spreadsheet). Refer to the example text file in resources.

CALCULATOR : Array Or Vector Dot Product [FREE] ±

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

CALCULATOR : Vector Cross Product [FREE] ±

Calculate the cross product of two arrays or vectors.

Enter the arrays or vectors as comma separated lists. Both arrays must have three elements. The cross product is an array, and it is perpendicular to both the input arrays. The cross product can be checked by checking that the cross product A · C = 0, and the cross product B · C = 0. The dot product of two perpendicular arrays is zero.

Tool Input

rndtype : Rounding Type For Small Values

Tool Output

chka : Check Dot Product A · C (== 0)
chkb : Check Dot Product B · C (== 0)
