    This is true independent of the value of since the equation for + is not needed to calculate the value of at points and . 3D centripetal Catmull-Rom spline segment. The extension to 3D points is simply achieved by considering P i = [ x i y i z i ] T {\displaystyle \mathbf {P} _{i}=[x_{i}\quad y_{i}\quad z_{i}]^{T}} a generic 3D point P i ...

  3. Full width at half maximum - Wikipedia

    en.wikipedia.org/wiki/Full_width_at_half_maximum

    In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y -axis which are half the maximum amplitude.

    Interpolation with cubic splines between eight points. Hand-drawn technical drawings for shipbuilding are a historical example of spline interpolation; drawings were constructed using flexible rulers that were bent to follow pre-defined points.

  6. Equivalent width - Wikipedia

    en.wikipedia.org/wiki/Equivalent_width

    The equivalent width of a spectral line is a measure of the area of the line on a plot of intensity versus wavelength in relation to underlying continuum level. It is found by forming a rectangle with a height equal to that of continuum emission, and finding the width such that the area of the rectangle is equal to the area in the spectral line.

  7. Spark (mathematics) - Wikipedia

    Equivalently, the spark of a matrix is the size of its smallest circuit (a subset of column indices such that = has a nonzero solution, but every subset of it does not [1]). If all the columns are linearly independent, s p a r k ( A ) {\displaystyle \mathrm {spark} (A)} is usually defined to be m + 1 {\displaystyle m+1} (if A {\displaystyle A ...
