over-determined system of equations AX=Y.
- @MMUL(M1, M2) -
- The product of multiplying matrix
M2 by matrix M1.
- @PLS(X, Y, d) -
- Analyzes the least squares polynomial
model Y=P(X), where P is a polynomial of
degree d.
- @POLYCOEF(X, Y, d) -
- The least squares coefficients for
the polynomial fit Y=P(X), where P is a polynomial of
degree d.
- @POLYFIT(X, Y, d) -
- The least squares polynomial fit,
given a vector of independent variables (X),
dependent variables (Y), and the degree (d)
of polynomial.
- @TRANSPOSE(M) -
- The transpose of matrix M.
- @TREND(NX, KX, KY) -
- The y values for new x
values given existing x and y values.
Embedded tools should not be contained within other functions or
arithmetic operations in a single formula. You may, however,
copy, move and format embedded tools just as any other function.
