transpose

Functions

int main(int argc, char *argv[])

transpose [ option ] [ infile ]

-r int
- number of rows \((1 \le M)\)
-c int
- number of columns \((1 \le N)\)
infile str
- double-type data sequence
stdout
- double-type transposed data sequence

The input of this command is

\[\begin{split} \begin{array}{cccc} x(0,0) & x(0,1) & \cdots & x(0,N-1) \\ x(1,0) & x(1,1) & \cdots & x(1,N-1) \\ \vdots & \vdots & & \vdots \\ x(M-1,0) & x(M-1,1) & \cdots & x(M-1,N-1) \end{array} \end{split}\]

and the output is

\[\begin{split} \begin{array}{cccc} x(0,0) & x(1,0) & \cdots & x(M-1,0) \\ x(0,1) & x(1,1) & \cdots & x(M-1,1) \\ \vdots & \vdots & & \vdots \\ x(0,N-1) & x(1,N-1) & \cdots & x(M-1,N-1) \end{array} \end{split}\]

where \(M\) is the number of rows and \(N\) is the number of columns. Note that \(x(m,n) \, \forall m \ge M\) are discarded.
