Ø  @DFT(R) -

The Discrete Fourier Transform of the range R.

 

Ø  @EIGEN(M) -

The eigenvalues of the matrix M.

 

Ø  @FFT(R) -

The Discrete Fourier Transform of the range R using a fast Fourier Transform algorithm.

 

Ø  @FREQUENCY(R, B) -

Returns a frequency distribution for values R with a set of intervals B.

 

Ø  @INVDFT(R) -

The inverse of the Discrete Fourier Transform of the range R.

 

Ø  @INVERT(M) -

The inverse of matrix M.

 

Ø  @INVFFT(R) -

The inverse of the Discrete Fourier Transform of the range R using a fast Fourier Transform algorithm.

Ø  @LLS(A, Y) -

The linear least squares solution X to the over-determined system of equations AX=Y.

 

Ø  @MMUL(M1, M2) -

The product of multiplying matrix M2 by matrix M1.

 

Ø  @PLS(X, Y, d) -

Analyzes the least squares polynomial model Y=P(X), where P is a polynomial of degree d.

 

Ø  @POLYCOEF(X, Y, d) -

The least squares coefficients for the polynomial fit Y=P(X), where P is a polynomial of degree d.

 

Ø  @TRANSPOSE(M) -

The transpose of matrix M.

 

Ø  @TREND(NX, KX, KY) -

The y values for new x values given existing x and y values.

 

Note

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.
