To plot this data in Matlab, you must interpolate the data on a uniform grid, as shown below. In the following example, notice that the Gaussian profile is not sampled uniformly in the Y direction. can you help me that how to get a 3d image using matlab. I have about 170 2D image slices of a brain. ![]() This is an important detail when plotting data obtained from a non-uniform mesh. Learn more about 2d image, 3d image, image processing, volume visualization Image Processing Toolbox. This is not true of the image command in the Lumerical script environment. The standard image command in MATLAB assumes that matrix data is uniformly sampled, even when you provide the x,y position vectors. ![]() % transpose matrix, plot data, add color barĢD image plot with non-uniform, rectilinear data MATLAB commands to generate equivalent plot To get the same figure orientation in MATLAB as in your Lumerical plots, you must apply an unconjugated transpose operation and adjust the axes, as shown below.ĢD image plot with uniform, rectilinear data MATLAB uses a different convention for plotting 2D matrix data than Lumerical. This page shows how to create 2D image plots of data from Lumerical's software using MATLAB.
