Performs two-dimensional interpolation on gridded points by using the bicubic interpolation method.
Use the bicubic method to perform interpolation within grid rectangles. The bicubic method ensures that the inside interpolated surfaces, their first partial derivatives, and the second-order mixed derivative all are continuous.
Tabulated values of the dependent variable.
Tabulated values of the independent variable in the x domain.
This input accepts a 1D or 2D array of double-precision, floating-point numbers.
All interpolation methods require that x be monotonic along each row, and all rows must be identical. Otherwise, this node uses only the first row of x to perform the interpolation. If x is not empty, the number of columns in x must equal the number of columns in z. If x is empty, this node treats x as an array whose size equals the size of z and whose rows are [0, 1, …, N - 1], where N is the number of columns in z.
Tabulated values of the independent variable in the y domain.
This input accepts a 1D or 2D array of double-precision, floating-point numbers.
All interpolation methods require that y be monotonic along each column, and all columns must be identical. Otherwise, this node uses only the first column of y to perform the interpolation. If y is not empty, the number of rows in y must equal the number of rows in z. If y is empty, this node treats y as an array whose size equals the size of z and whose columns are [0, 1, …, M - 1] T , where M is the number of rows in z.
Number of times that this node interpolates values repeatedly and evenly between each x and y element to generate xi used and yi used.
ntimes determines the locations of the interpolation values. If you wire data to xi or yi, this node ignores ntimes.
Default: 1
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Values of the independent variable in the x domain where interpolated values of the dependent variable are to be computed.
This input accepts a 1D or 2D array of double-precision, floating-point numbers.
xi and yi must be the same size.
Values of the independent variable in the y domain where interpolated values of the dependent variable are to be computed.
This input accepts a 1D or 2D array of double-precision, floating-point numbers.
xi and yi must be the same size.
Interpolated values of the new points that correspond to the independent variable values.
Values of the first independent variable at which interpolated values of the dependent variable are computed.
If you wire data to xi, xi used returns xi unchanged. Otherwise, xi used returns an array with identical rows of 2 ntimes - 1 points located evenly between each two adjacent elements in the first row of x, and the number of rows in xi used equals the number of rows in yi used.
Values of the second independent variable at which interpolated values of the dependent variable are computed.
If you wire data to yi, yi used returns yi unchanged. Otherwise, yi used returns an array with identical columns of 2 ntimes - 1 points located evenly between each two adjacent elements in the first column of y, and the number of columns in yi used equals the number of columns in xi used.
