Interpolating

PP = PCHIPD(X,Y,D) provides the piecewise cubic polynomial which interpolates values Y and derivatives D at the sites X. This is meant to augment the built-in Matlab function PCHIP, which does not allow the user to specify derivatives.X must be a vector.If Y and D are vectors, then Y(i) and D(i)...

PDL::GSL::INTERP is a PDL interface to Interpolation routines in GSL. SYNOPSIS use PDL; use PDL::GSL::INTERP; my $x = sequence(10); my $y = exp($x); my $spl = PDL::GSL::INTERP->init(cspline,$x,$y); my $res = $spl->eval(4.35); $res = $spl->deriv(4.35); $res = $spl->deriv2(4.35);...

Syntax:>> imagescnan(Z) % Uncolored NaNs>> imagescnan(Z,'k') % ColoredIMAGESC is a good option when the user doesn't like the interpolating behaviour of SURF or PCOLOR, because EVERY element is drawn as a single pixel CENTERED with the axis value.The problem with this function is that it doesn't...

Y = INPAINTN(X) replaces the missing data in X by extra/interpolating the non-missing elements. The non finite values (NaN or Inf) in X are considered as missing data. X can be any N-D array. Important note:----------------INPAINTN uses an iterative process that converges toward the solution. Y =...

When interpolating a multivalued function (more than one y for each x), interp1 produces, at best, an error (if there are identical x data), and at worst, garbage (see the attached image). This function performs meaningful interpolation of a multivalued function, when the inverse (x = g(y)) is a...

When interpolating on a given data set, convhull is used to set the boundaries of the interpolation area. Because convhull only minimizes the outline length, there might be interpolation lines which are unwanted (see figure).hullfit tries to minimze the polygon area instead resulting in a hull...

[Yinterp warningflag] = robustinterp(Xdata, Ydata, targetX)Linearly interpolates in columns of X and Y values with reversals or failures of strict monotonicity in x or y (e.g. noisy and/or quantized observations of ideally monotonic relationships).Ydata and Xdata are column vectors or matrices of...

This function uses a non-linear interpolation (Lagrange) to estimate y given x, based on a set of observed x-y points. Coordinates will be sorted based on the x-value of the pair. The x-value provided by the user to calculate y will be estimated using two points left and two points right of the...
