Matlab Meshgrid function Generation two-dimensional mesh matrix example explanation

usage is [x Y]=meshgrid (A, b);

Meshgrid

Where A and B are all one-dimensional arrays

Give some examples

1. A=[1 2 3] b=[2 3 4]

Then the resulting matrix X and y are all 3*3 matrices.

where each row of the x matrix is [1 2 3], the number of rows is determined by the length of the array b

Each column of the Y-matrix is [2 3 4], and the number of columns is determined by the length of the array a

>> [x Y]=meshgrid (A, B)
x =
1 2 3
1 2 3
1 2 3
y =
2 2 2
3 3 3
4 4 4

2.a=[1 2 3] b=[2 3]

The resulting x and y are all 3*2 matrices.

>> [x Y]=meshgrid (A, B)
x =
1 2 3
1 2 3
y =
2 2 2
3 3 3

where each row of the x matrix is [1 2 3], the number of rows is determined by the length of the array b

Each column of the y Matrix is [2 3], and the number of columns is determined by the length of the array A.

3.a=[1 2] b= [2 3 4]

The resulting matrices are all 2*3 dimensions.

>> [x Y]=meshgrid (A, B)
x =
1 2
1 2
1 2
y =
2 2
3 3
4 4

where each row of the x matrix is 1 2, the number of rows is determined by the length of the array B.

Each column of the Y-matrix is 2 3 4, and the number of columns is determined by the length of the array a
