Using the elements from A, create a 2-by-2-by-3 multidimensional array. As long as the number of elements in each shape are the same, you can reshape them into an array with any number of dimensions. For example, reshape a 3-by-4 matrix to a 2-by-6 matrix.
#Reshape matlab code
Here's the modified code that seems to work - error_row = 5 %// row index to be set as error rowīitstream = orignalPacket %// Assuming orignalPacket is of size 990 x 8īitstream(end+10,:)=0 %// pad with 10 rows of zeros at the end The reshape function changes the size and shape of an array. The problems you were encountering were because MATLAB uses column-major indexing and with your operations you were indexing into the matrices row-wise. Matrix_re=reshape(permute(reshape(bitstream_re,size(bitstream_re,2),8,),),8,) Newmatrix= reshape( bitstream.', ,psize) īitstream_re = reshape( newmatrix, ,1) īitstream_re(end-80+1:end)= %% Remove padding Please fix help me bitstream = reshape( orignalPacket.', ,1) %size 990 x 8īitstream(end+80)=0 % add zeros padding at the end It appeared some -1 in individual row (ex:, the true answer must be or because if row without error will only constain 0 or 1, and error row is only -1 values). Now I want to implement this scheme by matlab code. As long as the number of elements in each shape are the same, you can reshape them into. The array a is a 3-by-3 array we can add a third dimension to a, by providing the values like. a 7 9 5 6 1 9 4 3 2 MATLAB will execute the above statement and return the following result. The first issue to note is that twoD1 reshape(array1,, 20) does not do what you want since array1 is 400x400x20x24. B reshape (A,2,6) B 2×6 1 3 5 7 9 11 2 4 6 8 10 12. For example, let's create a two-dimensional array a. A 1 4 7 10 2 5 8 11 3 6 9 12 A 3×4 1 4 7 10 2 5 8 11 3 6 9 12. Imvect reshape (I,imsize, ) If you simply want to make you matrix I a vector of size (numel (I), 1), then you should use the colon operator :, as such: Imvect I (:) An alternative, if you really want to use reshape, is to specify that you want a single column, and let MATLAB select the number of rows, as such: Imvect reshape (I,, 1. It is very clear when you see the below figure. The reshape function changes the size and shape of an array. So, the number row error will be 400/8=50 rows The reshape function changes the size and shape of an array. Second step, I want to recovery my orignal matrix size 990 x 8 with that row error. First, I will reshape it to A x 400 where A will be determined s.t 990x8 is devisible by 400.
In Mathematica, the best equivalents for. When converting MATLAB code it might be necessary to first reshape a matrix to a. find() on a matrix returns them, whereas NumPy’s find behaves differently. Linear indices are common in MATLAB programs, e.g. In MATLAB, reshape (F,16,4) gives a 16×4 matrix, where column 1 is the first 16 elements of F, column 2 the 17th to 32nd, etc. RESHAPE and LINEAR INDEXING: MATLAB always allows multi-dimensional arrays to be accessed using scalar or linear indices, NumPy does not. I am working with matrix using reshape function. This gives a 64×1 column vector in Mathematica: as F (1:64)' does in MATLAB.
