How to plot multidimensional array with three. With the help of a 2D array, we can manipulate the matrix, the structure of the matrix contains the rows and columns and each value from the matrix contains the row index and column index. Any efficiency you might gain by using a single loop is negated by having to calculate the theta and phi based upon a single index. I'm looking to have a 3D representation of my 2D images where the 3rd dimension represents time. Reload the page to see its updated state. My ultimate goal is to be able to track a particular line across images and determine its path (or which image it originated from). Each element has two subscripts one is the row index and the other is the column index.

How many layers does Matlab handle well? For example with that one I can only increase both number until they get to 360x360 but I want that theta increases until 360 and then phi increases 1. Assume the MxN matrices only contain 0's and 1's. Unable to complete the action because of changes made to the page. MathWorks is the leading developer of mathematical computing software for engineers and scientists. The array 32x360x360 is 32xthetaxphi so I need first to run the theta values until 360 so phi increases in one. And sorry I meant 32x1x1, then 32x2x1, 32x3x1 so your technique is the one I needed. The data increases along the rows, I mean, each column has 32 points that are the plot of one curve, so I plot each time one curve, which would correspond to a value of theta and phi. @Jonas: Depends on plot size and memory; a few dozen before hitting memory problems for plots around 500x500 in 2 GB RAM. MathWorks ist der fhrende Entwickler von Software fr mathematische Berechnungen fr Ingenieure und Wissenschaftler. Concentration bounds for martingales with adaptive Gaussian steps. My concern with nave looping around A_a=A(A~=a(i)) is that, seemingly, for every element a(i), a comparison is made for every element in A, which ignores the underlying order in the 2 arrays. Like: Theta = 1, Phi = 1 ----> Theta = 2, Phi = 1 ----> Theta = 360, Phi = 1 ----> Theta = 1, Phi = 2 and so on. matlab: how to plot multidimensional array. All in One Data Science Bundle (360+ Courses, 50+ projects) Price View Courses If I have as input --> (5,10,2) = 2.5 Fifth row, 10 column and second row. Variables of velocities, temp and salinity are all multi dimensional arrays, containing the array sizes of the above variables.
