Clearly the first is the same but the latter is different. Is there some way to create the second variables (of form test2(a,b,c,d) test(d,b,a,c) which involve two permutations ) just using permute on test? This tutorial video demonstrates the basics of a row and column permutation matrix. This video is suitable for Year 12 VCE Further Maths students. Permute — Permute methodColumns (default) Rows. Method of constructing the output matrix by permuting rows or columns of the input. When the Permute parameter is set to: Rows –– The block uses the rows of A to create a matrix that has the same column dimension. 此 MATLAB 函数 按照向量 dimorder 指定的顺序重新排列数组的维度。例如，permute(A,2 1) 交换矩阵 A 的行和列维度。.

The Permute Matrix block reorders the rows or columns of an M-by-N input matrix A as specified by indexing input P.

Method of constructing the output matrix by permuting rows or columns of the input.
When the Permute parameter is set to:
Apple products compatible with fortnite. Rows –– The block uses the rows of A to create a matrix that has the same column dimension. Input P is a length-L vector whose elements determine where each row from A must be placed in the L-by-N output matrix.
For row permutation, the block treats the length-M unoriented vector input at the port A as an M-by-1 matrix.
Columns –– The block uses the columns of A to create a matrix that has the same row dimension. Input P is a length-L vector whose elements determine where each column from A must be placed in the M-by-L output matrix.
For column permutation, the block treats the length-N unoriented vector input at port A as a 1-by-N matrix.
When set to One-based, a value of 1 in the permutation vector P refers to the first row or column of the input matrix A. When set to Zero-based, a value of 0 in P refers to the first row or column of A.
Response to an invalid index value. When an index value in input P references a nonexistent row or column of matrix A, the block reacts as specified in this parameter. These options are available:
Clip index –– Clip the index to the nearest valid value (1 or M for row permutation and 1 or N for column permutation) and do not issue an alert. Example: For a 3-by-7 input matrix, a column index of 9 is clipped to 7 and a row index of -2 is clipped to 1.
Clip and warn –– Display a warning message in the MATLAB® Command Window and clip the index as described in the preceding bullet.
Generate error –– Display an error dialog box and terminate the simulation.
Tunable: Yes
Option to display an error dialog box and terminate the simulation when the length of the permutation vector P is not equal to the number of rows or columns of the input matrix A.
You can choose to open an error dialog box and terminate the simulation by setting this parameter to on.
Simulink® model example that shows how to permute a matrix by rows or columns.
The application envisioned for this example is automatic lane tracking on a road. D3 designer download. We will show how to fit a polynomial to noisy data representing the lane boundary of the road ahead of a vehicle.
