function B = permute(A, order) %PERMUTE Permute symbolic array dimensions. % B = PERMUTE(A,ORDER) rearranges the dimensions of A so that they % are in the order specified by the vector ORDER. The array produced % has the same values as A but the order of the subscripts needed to % access any particular element are rearranged as specified by ORDER. % For an N-D array A, numel(ORDER)>=ndims(A). All the elements of % ORDER must be unique. % % PERMUTE and IPERMUTE are a generalization of transpose (.') % for N-D arrays. % % Example: % a = sym(ones(1,2,3,4)); % size(permute(a,[3 2 1 4])) % now it's 3-by-2-by-1-by-4. % % See also SYM/TRANSPOSE. % Copyright 2013 The MathWorks, Inc. narginchk(2,2); if ~isnumeric(order) && ~isa(order,'sym') error(message('symbolic:permute:badIndexType')); end if ~isa(A,'sym') B = permute(A,double(order)); return; end B = privBinaryOp(A, order, 'symobj::permute'); end
