Inside a structure are a list of fields each being a variable name for some sub-piece of data. MATLAB (matrix laboratory) is a numerical computing environment and fourth-generation programming language. Simply import the points into Matlab from the TSV file then create a surface plot from these points. If you can represent your geometry as a collection of n-sided polygons, you can pass this to function decsg. Then you edit and put all the data on one work sheet then you read it into CFD-Post to start your data analysis. clc clear x0=-1; x00=1; y0=1; y00=-1; M=30; N=30; dx=(x00-x0)/M; dy=(y00-y0)/N; [x,y] = meshgrid(x0:dx:x00,y0:dy:y00); for i=1:M+1; for j=1:N+1; z(i,j)=0; end. However, an alternative is to use the PDE Toolbox command-line API.
