This question already has an answer here: How to create a 2D-matrix out of my data for surf()? 2 answers I have a set of 3D data which are not ordered. I need to plot a surface which basically connects them together and color the surface based on my...

I have 3 sets of 3D co-ordinates and I have fitted planes to each set. Now, I want to plot all the data points and the 3 planes in one figure. So far, I have the following function: function [fitresult, gof] = create_fit(xx, yy, zz, grp) [xData, yData, zData] =...

I have a surface in matlab which is plotted using the following code: [xi, yi] = meshgrid(S/K, days); vq = griddata(S/K, days, rbf/K, xi, yi,'natural'); mesh(xi,yi,vq) The resulting image is quite rough, and has lots of grid lines as there are roughly 200 data points in each vector. Is it...

Good day everyone; I have a M*N matrix and I have two coordinate vectors X and Y, where X has the length of M and Y has the length of N but they have different values because M is an array index and X is a Latitude coordinate, for example...

I am currently trying some things using pixel manipulation and I would like to set the pixel format of a SDL_Surface. The problem here is that I am loading up an image with the SDL_image.h. So I have to create a texture from a surface like this: surface = IMG_Load(filePath);...

When I run following script in R, the fitted line doesn't appear in the plot. I want it to appear though. Can you help me? rm(list=ls()) # Surface tension surft <- c(49.1, 51.7, 50.7, 52.0, 53.5, 52.9, 55.1, 59, 62.5, 66.4, 69.0, 73.8) # surface tension of mixtures # Mole...

Lets consider that I have five 2D-Matrices which describe the magnetic field at different z-Layers. A nice, smoothed version of a 2D-Surface plot can be obtained as follows: data2_I<-matrix(c(1.0,1.0,0.6,0.6,0.7,0.9,0.9,0.5,0.5,0.5,0.7,0.9,0.9,0.6,0.3,0.4,0.7,0.9,0.9,0.7,0.5,0.5,0.6,0.9,0.9,0.7,0.6,0.6,1.0,1.0), nrow=5) Z = as.vector(data2_I) length(Z) XY=data.frame(x=as.numeric(gl(5,1,30)),y=as.numeric(gl(5,6,30))) t=Tps(XY,Z) surface(t) Now it would be great if I could get a 3D-plot where at...
