  2. List of arbitrary-precision arithmetic software - Wikipedia

    en.wikipedia.org/wiki/List_of_arbitrary...

    ColdFusion: the built-in PrecisionEvaluate() function evaluates one or more string expressions, dynamically, from left to right, using BigDecimal precision arithmetic to calculate the values of arbitrary precision arithmetic expressions. D: standard library module std.bigint; Dart: the built-in int datatype implements arbitrary-precision ...

  3. Normalized frequency (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Normalized_frequency...

    Some programs (such as MATLAB toolboxes) that design filters with real-valued coefficients prefer the Nyquist frequency (/) as the frequency reference, which changes the numeric range that represents frequencies of interest from [,] cycle/sample to [,] half-cycle/sample. Therefore, the normalized frequency unit is important when converting ...

  4. LOBPCG - Wikipedia

    en.wikipedia.org/wiki/LOBPCG

    A simple work-around is to negate the function, substituting -D T (D X) for D T (D X) and thus reversing the order of the eigenvalues, since LOBPCG does not care if the matrix of the eigenvalue problem is positive definite or not. [9] LOBPCG for PCA and SVD is implemented in SciPy since revision 1.4.0 [13]

    That is, the encoding function is defined via = (()) {,}. The fact that the codeword C ( x ) {\displaystyle C(x)} suffices to uniquely reconstruct x {\displaystyle x} follows from Lagrange interpolation , which states that the coefficients of a polynomial are uniquely determined when sufficiently many evaluation points are given.

  6. Multiply–accumulate operation - Wikipedia

    en.wikipedia.org/wiki/Multiply–accumulate...

    With GCC, which does not support the aforementioned pragma, [12] this can be globally controlled by the -ffp-contract command line option. [13] The fused multiply–add operation was introduced as "multiply–add fused" in the IBM POWER1 (1990) processor, [14] but has been added to numerous other processors since then: HP PA-8000 (1996) and above

  7. Round-off error - Wikipedia

    en.wikipedia.org/wiki/Round-off_error

    In the IEEE standard the base is binary, i.e. =, and normalization is used.The IEEE standard stores the sign, exponent, and significand in separate fields of a floating point word, each of which has a fixed width (number of bits).

  9. Chebyshev filter - Wikipedia

    en.wikipedia.org/wiki/Chebyshev_filter

    If it is not feasible to design the filter with one of the terminations increased or decreased to accommodate the pass band S12, then the Chebyshev transfer function must be modified so as to move the lowest even order reflection zero to = while maintaining the equi-ripple response of the pass band.
