| Description:<br> | ||
| <br> | ||
| Given a set of data points (x[i], y[i], z[i]) representing a surface<br> | ||
| z=f(x,y), compute a B-spline representation of the surface.<br> | ||
| <br> | ||
| Inputs:<br> | ||
| <br> | ||
| x, y, z -- Rank-1 arrays of data points.<br> | ||
| w -- Rank-1 array of weights. By default w=ones(len(x)).<br> | ||
| xb, xe -- End points of approximation interval in x. <br> | ||
| yb, ye -- End points of approximation interval in y.<br> | ||
| By default xb, xe, yb, ye = x[0], x[-1], y[0], y[-1]<br> | ||
| kx, ky -- The degrees of the spline (1 <= kx, ky <= 5). Third order<br> | ||
| (kx=ky=3) is recommended.<br> | ||
| task -- If task=0, find knots in x and y and coefficients for a given<br> | ||
| smoothing factor, s.<br> | ||
| If task=1, find knots and coefficients for another value of the<br> | ||
| smoothing factor, s. bisplrep must have been previously called<br> | ||
| with task=0 or task=1.<br> | ||
| If task=-1, find coefficients for a given set of knots tx, ty.<br> | ||
| s -- A non-negative smoothing factor. If weights correspond to the inverse<br> | ||
| of the standard-deviation of the errors in z, then a good s-value<br> | ||
| should be found in the range (m-sqrt(2*m),m+sqrt(2*m)) where m=len(x)<br> | ||
| eps -- A threshold for determining the effective rank of an over-determined<br> | ||
| linear system of equations (0 < eps < 1) --- not likely to need<br> | ||
| changing.<br> | ||
| tx, ty -- Rank-1 arrays of the knots of the spline for task=-1<br> | ||
| full_output -- Non-zero to return optional outputs.<br> | ||
| nxest, nyest -- Over-estimates of the total number of knots. If None then<br> | ||
| nxest = max(kx+sqrt(m/2),2*kx+3),<br> | ||
| nyest = max(ky+sqrt(m/2),2*ky+3)<br> | ||
| quiet -- Non-zero to suppress printing of messages.<br> | ||
| <br> | ||
| Outputs: (tck, {fp, ier, msg})<br> | ||
| <br> | ||
| tck -- A list [tx, ty, c, kx, ky] containing the knots (tx, ty) and<br> | ||
| coefficients (c) of the bivariate B-spline representation of the<br> | ||
| surface along with the degree of the spline.<br> | ||
| <br> | ||
| fp -- The weighted sum of squared residuals of the spline approximation.<br> | ||
| ier -- An integer flag about splrep success. Success is indicated if<br> | ||
| ier<=0. If ier in [1,2,3] an error occurred but was not raised.<br> | ||
| Otherwise an error is raised.<br> | ||
| msg -- A message corresponding to the integer flag, ier.<br> | ||
| <br> | ||
| Remarks:<br> | ||
| <br> | ||
| SEE bisplev to evaluate the value of the B-spline given its tck<br> | ||
| representation.</tt></dd></dl> | ||
