Matlab Plot 3d Surface Data Points

I have a set of points from a complex function that i am trying to produce a 3d shape of and have had no luck so far.

Matlab plot 3d surface data points. Cite 28th jan 2015. I used python to find the points in a txt format. The values v must be a column vector of length npts. Here we have taken an example of 2d to 3d conversion as it is also one of the most significant and common application used in all matlab applications.

In general the three dimensional plots consist of the three vectors xyz in the same graph. When those 10 points are connected it forms a line curve which is what you see when you plot the variables with plot3. The 4 graphs are valid the 1st one is just showing the location of the points in 3d the 2nd 3rd and 4th are almost the same but the last one is more smoother. Causes the surface plot to break down into a 2d heatmap.

Im z50 meshgridim z50. Therefore at each im or z50 there are 10 data from mnxdisp data set. Surely there must be a way to co plot points onto a 3d surface plot. The plot is formed by joining adjacent points with straight lines.

The matrix contains potential data in a grid cube the plot is basically a 3d xyz grid that contains potential data at those each xyz point. Functions for plotting data grids. When i do this the 3d surface plot breaks down. The general syntax to display the 3d plot is.

It produces a wireframe surface 2. Surface plots are useful for visualizing matrices that are too large to display in numerical form and for graphing functions of two variables. The data abe been like these first. From there i copy the data to excel to transpose the columns into rows for matlab use.

Its unclear to us how those data can be extended to illustrate a surface. I am struggling a bit here and hope somebody could help. Even in the absence of the plot3 command just adding the hold onhold off. The sample points x must have size npts by 2 in 2 d or npts by 3 in 3 d where npts is the number of points.

You can also use a specified line style marker and color for drawing 3d plots. I wonder if it is possible to fit 20 curves and then plot a surface. In matlab the plot3 function is used to draw the 3d plot graph. If z were a matrix of size numel x numel y then you could use meshgrid or ndgrid to expand the x and y values in order to plot a surface.
