Crspoint
Gets the intersection between 2 straight lines.
Format
Crspoint <line1()>, <line2()>, <x>, <y>
Parameter
Return value
None.
Description
Gets the intersection point of the line component specified in the <line1()> parameter and the line component
specified in the <line2()> parameter. In the <x> parameter and <y> parameter, specify the respective
variables that will hold the X coordinate and Y coordinate of the intersection point.
In the <line1()> parameter and in the <line2()> parameter, specify a 1D double precision real number array
with "a" in element 0, "b" in element 1, and "c" in element 2, where a, b, and c satisfy the linear equation ax +
by + c = 0 , without adding element numbers but adding () to the variables.
This macro function is mainly used to get the intersection point of lines gotten with the Lsqumeth function.
If an undefined array is specified a parameter, an "Undefined label" error will occur.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a non-existent number, numerical value, or combination of data types or values are specified for a
parameter, an "Illegal function call" error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
