Lsqumeth
Gets the approximate straight line from the coordinates of multiple points using the least squares method.
Format
Lsqumeth <count>, <x()>, <y()>, <line()>
Parameter
Return value
None.
Description
Gets the approximate straight line from the coordinates specified in the <x()> parameter and <y()> parameter.
The number of coordinates is specified in the <count> parameter.
In the <line()> parameter, specify the variable that will hold the line components of the gotten approximate
straight line, without adding element numbers but adding () to the variables. In the <line()> parameter, the
parameters a, b, and c that satisfy the linear equation ax + by + c = 0 are stored in the array elements of the
double precision real number array variable, with "a" in element 0, "b" in element 1, and "c" in element 2.
In the <count> parameter, specify an integer value of at least 2.
In the <x()> parameter and in the <y()> parameter, specify a 1D double precision real number array variable
that stores a number of coordinate values greater than or equal to the number specified in the <count>
parameter, without adding element numbers but adding () to the variables.
This macro function is mainly used to get the straight line of an edge from the measurement points gotten in
multiple edge measurements.
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 is 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.
