C Mat Rows
In every column and every row of the square matrix the values are repeated.
C mat rows. C mat for every row of c i want to find all the elements in column a that are in a time window centered on the first element of column a at the first iteration of 4 minutes. Mat e a range all range 1 3. Consequently the product rows cols channels must stay the same after the transformation. Make a numpy array of every row and every column in the square matrix.
The idea is to use the numpy library. Number of rows columns mat x 3 2 2 2 4 6 3 1 mat lis x x 4 2 c1 c2 r1 3 2 r2 2 2 r3 4 6 r4 3 1 scalar r rowsof x scalar c colsof x display r c 4 2 computing column row sums. No data is copied. Using row and column boundaries now you may ask if the matrix itself may belong to multiple mat objects who takes responsibility for cleaning it up when it s no longer needed.
That is this is an o 1 operation. This dimension becomes 1 while the sizes of all other dimensions remain the same. This application will be a library dll or so in order to be used by other langage like java trough jna. If a is a vector then mean a returns the mean of the elements.
If a is a matrix then mean a returns a row vector containing the mean of each column. Consequently if you change the number of rows or the operation changes the indices of elements row in some other way the matrix must be continuous. I will create a application c wich will do some image processing and return a image. Therefore the total count is 4 for both rows and columns.
