wish help you to fix your issue The answer is to use the permute command: code :
permute([1 2 3 4 5 6], [3 1 2])

MATLAB: why transpose single dimension array
By : Satrajit Das

wish helps you All "arrays" in MATLAB have at least two dimensions, and can be treated as having any number of dimensions you wish. The transpose operator here is converting between a row (size [1 N] array) and a column (size [N 1] array). This can be significant when it comes to either concatenating the arrays, or performing other operations. Conceptually, the dimension vector of a MATLAB array has as many trailing 1s as is required to perform an operation. This means that you can index any MATLAB array with any number of subscripts, providing you don't exceed the bounds, like so: code :
x = magic(4); % 4by4 square matrix
x(2,3,1,1,1) % pick an element

multiply numpy.array a with leading dimension of numpy.array b

To fix the issue you can do I have two numpy arrays, a and b, where a has dimension 1 and the same length as the leading dimension as b, e.g., , You could use code :
(a * b.T).T
(a*b.T).flags.contiguous
# False
(a*b.T).T.flags.contiguous
# True

it should still fix some issue A table , A bit verbose but here it is code :
SELECT array_agg(v ORDER BY j) matrix FROM (
SELECT rn, j, array_agg(v ORDER BY i) AS v FROM (
SELECT rn, i, j, matrix[i][j] AS v FROM (
SELECT generate_subscripts(matrix, 2) j, q.* FROM (
SELECT ROW_NUMBER() OVER () AS rn,
generate_subscripts(matrix, 1) AS i,
matrix
FROM matrices
) q
) r
) s
GROUP BY rn, j
) t
GROUP BY rn
ORDER BY rn;
CREATE OR REPLACE FUNCTION transpose_2d(anyarray)
RETURNS anyarray AS $$
SELECT array_agg(v ORDER BY j) matrix FROM (
SELECT j, array_agg(v ORDER BY i) AS v FROM (
SELECT i, j, $1[i][j] AS v FROM (
SELECT generate_subscripts($1, 2) j, q.* FROM (
SELECT generate_subscripts($1, 1) AS i, $1
) q
) r
) s
GROUP BY j
) t
$$ LANGUAGE sql IMMUTABLE;
SELECT transpose_2d(matrix)
FROM matrices;
matrix

{{1,4},{2,5},{3,6}}
{{a,d},{b,e},{c,f}}
(2 rows)

C++: Transpose of Matrix, using SINGLE DIMENSION dynamic array to save elements

With these it helps Dear Friends I am having problem to transpose a matrix. The transposed matrix has elements that are undefined. Not sure what is wrong. Thank you for your time! , When the matrix is not square, the line code :
temp[(j  1) * m + i  1] = entries[(i  1) * m + j  1];
temp[(j  1) * n + i  1] = entries[(i  1) * m + j  1];
// ^^ needs to be n, not m.
temp[j][i] = entries[i][j];
