Display Name	Variable Name	I/O and Type	Default Value	Description
Input Matrix	im	Input MatrixObject	<active>	The matrix that contains the input data
Method	method	Input int	spline	Interpolation method. Option list Nearest Interpolate using the nearest points. Bilinear Two dimensional linear interpolation. Bicubic Convolution Two dimensional interpolation using bicubic convolution. Spline Two dimensional spline interpolation. Biquadratic Two dimensional quadratic interpolation. Bicubic Lagrange Two dimensional interpolation using Lagrange polynomials.
Number of Cols	cols	Input int	<auto>	The number of columns in the output matrix
Number of Rows	rows	Input int	<auto>	The number of rows in the output matrix
Missing Value Pretreatment	missing	Input int	<auto>	Preprocess missing values in 2D interpolation. Option Lists: 0=skip:Skip Remove all missing values first and then run interpolation. 1=rc:Interpolated with Renka Cline Renka Cline: For an arbitrary point P, compute the interpolated value using the data values and gradient estimates at each of the three vertices of the triangle which contains P.
First X	xmin	Input double	<auto>	The minimum x value of the output matrix
Last X	xmax	Input double	<auto>	The maximum x value of the output matrix
First Y	ymin	Input double	<auto>	The minimum y value of the output matrix
Last Y	ymax	Input double	<auto>	The maximum y value of the output matrix
Output Matrix	om	Output MatrixObject	<new>	The output matrix See the syntax here.

Select File: Open from the Origin menu to bring up the Open dialog. With the Files of Type drop-down list, select Matrix (*.ogm). Browse to \Samples\Matrix Conversion and Gridding\ folder under the Origin programming folder. And open 2D Gaussian.ogm.
Select Analysis: Mathematics: 2D Interpolate/Extrapolate from the Origin menu to open the minterp2 X-Function.
Enter 20 on the Number of Cols and Number of Rows edit box. And select spline as the Method.
Click OK to perform the interpolation.
