Concatenation method The dimension along which to concatenate the inputs. Number of inputs The number of matrices to concatenate. When all inputs to the Matrix Concatenation block are length-M i 1-D vectors, the output is a M i-by-1 matrix containing all input elements concatenated in port order: the elements in the vector input to the top port appear as the first elements in the output, and the elements in the vector input to the bottom port appear as the last elements in the output. (1-D vector inputs are not accepted for vertical concatenation when the other inputs have column dimension greater than 1.) When some of the inputs are length-M i 1-D vectors while others are M i-by-1 matrices, the vector inputs are treated as M i-by-1 matrices.

Cpermute(B,3 2 1) permute to the correct order. B repmat(A,1,10,10) use repmat to create a 3x10x10 copy. The output matrix has dimension M i-by-N, where M i is the number of rows in input u i ( i = 1, 2, ., n). The need for the permute arises from the use of column-major order by repmat, requiring you to first create the three correct 10x10 slices, then switch the first and third dimensions using permute. When the Concatenation method parameter is set to Vertical, the block concatenates the input matrices along columns.įor vertical concatenation, inputs must all have the same column dimension, N, but can have different row dimensions. When some of the inputs are length-M 1-D vectors while others are M-by-N i matrices, the vector inputs are treated as M-by-1 matrices. The output matrix has dimension M-by- N i, where N i is the number of columns in input u i ( i = 1, 2, ., n).

When the Concatenation method parameter is set to Horizontal, the block concatenates the input matrices along rows. If all inputs are sample-based, the output is sample-based.

The Matrix Concatenation block concatenates input matrices u 1, u 2, ., u n along rows or columns, where n is specified by the Number of inputs parameter. Matrix Concatenation (Simulink Reference) Simulink ReferenceĬoncatenate inputs horizontally or vertically
