建设网站的工作推广方案怎么做

计算矩阵中每个点的坐标

给定左上角、左下角和右上角三个点的坐标，以及矩阵的行数、列数、行间距和列间距，我们可以计算出所有点的坐标。
在项目中有一个运动装置，只可按照x或y方向移动。目标是在96孔板的96个孔，而这些孔是排列整齐有序的，那么我们就可通过该方案计算出剩余的点，来简化示教人员的工作。

代码实现

public class PlateWellPoint
{public double X { get; }public double Y { get; }public int RowIndex { get; set; }public int ColumnIndex { get; set; }public PlateWellPoint(double x, double y){X = x;Y = y;}public override string ToString(){return $"R{RowIndex}C{ColumnIndex}({X:F2}, {Y:F2})";}
}

案例图

调用验证

var leftTop = new PlateWellPoint(2, 2);
var rightTop = new PlateWellPoint(6, 6);
var leftButtom = new PlateWellPoint(4, 0);
int rowCount = 3;
int columnCount = 5;
var points = PlatePointMatrixGenerator.GeneratePoints(leftTop, leftButtom, rightTop, rowCount, columnCount, 1, 1);

运行结果

注意：行列序号从0开始的。

从上述结果中随便选一个点，在案例图中找到进行坐标验证
例如：取索引为13的点，是R2C3即第三行第四列，在案例图中核对坐标是否为x:7,y:3。
从案例图中任选一个坐标点，在上述结果中查找，是否为指定的行和列。
