min

min (replaces TMin)

The min function returns the minimum value of a 1-dimensional array, CImage , or list of numbers. The list of numbers must contain a mixture of numbers and strings that can be converted to numbers. This function is similar to the CStat:Min method but does not require calling new_stats() beforehand to create a CStats object. The related minxy function returns the minimum value and coordinates of the minimum value.

Whereas this function operates on a pure (indexed) array, the slightly slower minn function returns the minimum value in a general n-dimensional table.

Syntax

nMin = min( Data )

nMin = min( n1, n2, n3, ... )

Data is a 1-dimensional array, list of numbers, or a CImage object.

n1, n2, n3, ... are numbers or string values that can be converted to numbers.

nMin is the returned minimum value found in Data.

Remarks

All table types except for the CImage class real numbers with pixel type "double". The CImage class supports values ranging from byte to double plus other pixel types.

For a CMatrix, the returned nX and nY can be difficult to untangle because the CMatrix does not require a fixed number of columns in each row.

Examples

The following script returns the minimum value of a table containing 1 million random numbers.

t = random( 1000000 )	-- create a table of numbers
v = minxy( t )	-- find the minimum
Printf("Min = %lg\n", v )	-- list the minimum value

The next script returns the minimum value for pixels in a CImage.

V = AttachView( "CImageView" )	-- attach the topmost image window
Assert( V and V:Count() > 0 )	-- make sure an image window is on top
v = min( V:GetImage() )	-- find the minimum value in the CImage
Printf("Min = %lg\n", v )	-- list the minimum value

The next example computes the minimum value of a list of numbers:

v = min( 5, 6, "-2", 5.4 }	-- find the minimum value
Printf("Min = %lg\n", v )	-- result: Min = -2
