The core idea is, starting from the beginning of the state, according to the grammar expansion, progressive analysis of the state, until the analysis is completed, if there is a state mismatch, that is, syntax errors, stop analysis. Of course, the actual parser should have the error recovery mechanism to discover other gra
Multivariate linear regression model: y = b1x1 + b2x2 + b3x3 + ... +bnxn;We are based on a set of data: similar to arr_x = [[1, 2, 3, 4, 5], [6, 7, 8, 9, 10], [11, 12, 13, 14, 15]]; Arr_y = [5, 10, 15]; The last we asked for was an array that contained the B1 to Bn;Methods: Using least squares methodFormula: We only use the first half of the formula, that is, the matrix to calculateThe x in the formula is arr_x, a two-dimensional array we can think of as a matrix, the y in the formula is arr_y,

When working with data in Excel, whether it's using VBA or functions, finding and referencing are two major tasks, the method of the Find series in VBA (Find, FindNext, range.findprevious) Returns a Range object that can be found and referenced at the same time, so it is useful to have some common find usages listed below:Sub Find1 () ' Find in a columnDim KK = Range ("A:a"). Find ("A"). RowMsgBox KEnd Sub==============================================
