meshgrid(x,y) returns 2-D grid coordinates based on the coordinates contained in vectors x and y. X is a matrix where each row is a copy of x, and Y is a matrix where each column is a copy of y. The grid represented by the coordinates X and Y has length(y) rows and length(x) columns. example. [X,Y] =.
You can create x1g and x2g using the MATLAB meshgrid command. Given two free variables, x1 and x2, you can create the first and second coordinate matrices of a grid by entering: >> [x1g,x2g]=meshgrid(x1,x2); To summarize, here are the required steps to define and visualize a function of two variables. First, define the free variables:
24 Οκτ 2013 · Say you want to know the row/column/etc indices of an array. You can use meshgrid for that, but it will output first the column, then the row indices, which can be a source of error. Instead of meshgrid, you can use ndgrid, which will give the indices in the expected order, i.e.
The main difference between the outputs of MESHGRID and NDGRID has to do with how data is visualized. MESHGRID produces data that is oriented in Cartesian coordinates, generally a more expected view. For example, if I use the command:
meshgrid. Generate X and Y matrices for three-dimensional plots. Syntax [X,Y] = meshgrid(x,y) [X,Y] = meshgrid(x) [X,Y,Z] = meshgrid(x,y,z) Description [X,Y] = meshgrid(x,y) transforms the domain specified by vectors x and y into arrays X and Y, which can be used
Meshgrid creates multi-dimensional matrices from vectors which allows us to do higher operations over several spaces with ease. Suppose we have a function of two variables: f(x,y) = xy, and suppose we know the domain of each variable: domain of x is (1,4) and the domain of y is(10, 40).
Using the MATLAB Meshgrid Command and Array Operators to Implement One-and Two-Variable Functions. One of the more difficult topics covered in our MATLAB Fundamentals course is the use of array operators on matrices to implement functions of one and two variables.
