The problem is that its not very easy to look at the 3d plot produced. If I could somehow look at it from the opposite side or reverse the bottom axis so they went from 70 to 30 (instead of 30 to 70), I could then get a plot that would view better Accepted Answer: James Tursa. I have it right for one half of the assignment (4 elements) but not the other. The second part that I have wrong is 3 elements. Theme. Copy. function mileMarkers = ReverseArray (mileMarkers) % mileMarkers: Row array of mile marker values. % Reverse the contents of row array mileMarkers Description. B = flipud (A) returns A with its rows flipped in the up-down direction (that is, about a horizontal axis). If A is a column vector, then flipud (A) returns a vector of the same length with the order of its elements reversed. If A is a row vector, then flipud (A) simply returns A. For multidimensional arrays, flipud operates on the Get your 2D matrix pages into the 1st two dimensions. This makes each 2D page contiguous in memory and is somewhat of an unwritten standard for many other functions that operate on 2D pages M = flipdim(M, 2); This flips an N dimensional matrix along the dimension you specify as the second parameter. Thus, the flipud could be replaced with. M = flipdim(M, 1); Not sure where you are going with the repmat question, but I often find I can use bsxfun instead of repmat. Look it up Description. B = squeeze (A) returns an array with the same elements as the input array A, but with dimensions of length 1 removed. For example, if A is a 3-bybyby-2 array, then squeeze (A) returns a 3-by-2 matrix. If A is a row vector, column vector, scalar, or an array with no dimensions of length 1, then squeeze returns the input A Reverse the X and Y axis values in a 3D plot - MATLAB Answers - MATLAB Central.

Description. example. newStr = reverse (str) reverses the order of the characters in str. Examples. collapse all. Reverse Strings. Reverse the strings in a string array and find B = sort (A) sorts the elements of A in ascending order. If A is a vector, then sort (A) sorts the vector elements. If A is a matrix, then sort (A) treats the columns of A as vectors and sorts each column. If A is a multidimensional array, then sort (A) operates along the first array dimension whose size does not equal 1, treating the elements From what I understand, you just want to sort by an element on each page in the 3D array - this is how you can do it: Theme. A = randi (10, [4,4,4]) [~,idx] = sort 6. In Matlab, sort returns both the sorted vector and an index vector showing which vector element has been moved where: [v, ix] = sort(u); Here, v is a vector containing all the elements of u, but sorted. ix is a vector showing the original position of each element of v in u. Using Matlab's syntax, u (ix) == v The procedure is: Compute vector of inner products between doc idx and all other documents. Sort in descending order. Return the "scores" and indices from the second one to the end (i.e. not itself) The code I have at the moment is: import h5py. import numpy as np. def get_related(tfidf, idx): ''' return the top documents ''' Plot3 (X,Y,Z) plots coordinates in 3-D space. To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors. example. plot3 (X,Y,Z,LineSpec) creates the plot using Sort index, returned as an index vector. The sort index describes the rearrangement of the rows in the input such that B = A(index:). The sortrows function uses a stable sorting algorithm. So, when the input contains repeated values, the sort index preserves the original order from the input, regardless of sorting direction Surface Plot (with Shading) The surfl function creates a surface plot with colormap-based lighting. For smoother color transitions, use a colormap with linear intensity variation such as pink

If you want to reverse, stay away from sort. If you want to sort, by all means but that's not what this question needs. – NeilG. Mar 21, at Add a comment | 5 If you want to do an in-place reverse sort, you can also do this: [HOST](reverse=True) Share Description. B = permute (A,dimorder) rearranges the dimensions of an array in the order specified by the vector dimorder. For example, permute (A, [2 1]) switches the row and column dimensions of a matrix A. In general, the ith dimension of the output array is the dimension dimorder (i) from the input array
