The Digital Terrain Model (DTM) was originally proposed for the Automatic Design of highways (Miller, 1956 ). Since then, it has been used for the design of various line selection (railway, highway, transmission line), calculation of the area, volume, and slope of various projects, the cross-view judgment between any two points and the drawing of any broken line. It is used to draw contour lines, slope and slope directions, and three-dimensional persp

We then create the train and test subsets. The dataset is still fairly unbalanced, so we don ' t just randomly assign data points to the train and test datasets; We make sure to preserve the percentage of good reads in each subset by using the caret function ' createdatapartition ' for Stratified

ID Card Verification The simplest is the length of the judgment, of course, this is very simple to break if you want more rules we need to do some of the ID card number according to the generated rules to verify, the following sorting out some of the functions we have to look at.
Example, share today a PHP Verified ID card number is the correct function.
/********************php Verify that the ID number is correct function *********************/functions Is_idcard ($id) {$id = Strtoupper ($id)
This paper mainly introduces the function of verifying the identity card of PHP. Have a good reference value, follow the small series together to see it
If you don't say much, look at the code:
function Is_idcard ($id) {$id = Strtoupper ($id); $REGX = "/(^\d{15}$) | (^\d{17} ([0-9]| X) $)/"; $arr _split = Array (); if (!preg_match ($REGX, $id)) {return FALSE; } if (15==strlen ($id))//Check 15-bit {$regx = "/^ (\d{6}) + (\d{2}) + (\d{2}) + (\d{2}) + (\d{3}) $/"; @preg_match ($REGX, $id
ID card Verification is the simplest way to judge the length of the, of course, this very simple broken if you want to more regular we need to do some of the ID number according to the build rules to verify that some of the following functions we take a look.
Example, today share a PHP verification ID number is the correct function.
/********************php Verify that the ID number is correct *********************/function Is_idcard ($id) {$id = Strtoupper ($id); $REGX = "/(^\d{15}$) | (^
This article mainly for you to share the two paragraph PHP verification ID card number is the correct function, interested in small partners can refer to
