rows = (x.sum(-1) % 2) == 0 columns = [0, 2] x[np.ix_(rows, columns)] # [[3,5],[9,11]] 1. 2. 3. 4. 5. 6. 7. 这里的np.ix_表示网状扩展。
You create 2 helper formulas (a column match and a row match. Then your INDEX formula just brings back the value from the cell with those coordinates. This formula then still works correctly even if your Pivot table columns are re-ordered or new one is added / disappears or if a new co...
(i.e., the number of rows, columns, and pages) and either one or two arrays of data. The first array stores the real part of the array data and the second array stores the imaginary part. For arrays with no imaginary part, the second array is not present. The data in the array ...

If A is a table or timetable, then sz is a two-element row vector containing the number of rows and the number of variables. Multiple columns within a single variable are not counted. If A is a character vector of type char, then size returns the row vector [1 M] where M is the...
Takes any number of cell or double arrays and resizes them all to the same dimensions. Also serves to resize any array with removal of extra rows/columns and adding of NaN, 0, or empty string rows/columns. - NotMyMajor/MATLAB_samesize
