MAX

MAX (LET)

Library Function

Return the maximum of 2 to 8 numbers.

LET <yout> = MAX(<y1>,..., <yk>)
                        <SUBSET/EXCEPT/FOR qualification>
where <y1>, ..., <yk> is a list of one to eight variable or parameters;
            <yout> is a variable or a parameter (depending on what <y1> ... <yk> are) where the computed response values are stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

LET A = MAX(14,10)
LET A = MAX(A1,A2)
LET A = MAX(A1,A2,A3,A4)
LET X2 = MAX(X1,X4)
LET X2 = MAX(X1-4,X2+6)

This function is distinct from the LET subcommand MAXIMUM. This command compares two through eight parameters (or a pairwise comparison of the corresponding elements in two through eight variables) while MAXIMUM returns the largest value in a single variable.

The 2010/12 version of Dataplot added support for up to eight input arguments. For example,
LET AMAX = MAX(A1,A2,A3,A4,A5,A6,A7,A8)

Versions prior to this only accepted two input arguments.

None

MIN	=	Compute the minimum of two through eight numbers.
MAXIMUM	=	Compute the maximum value in a variable.
MINIMUM	=	Compute the minimum value in a variable.
ABS	=	Compute the absolute value of a number.

2010/12: Support for up to eight input arguments

 
LET X = SEQUENCE 0 .1 3
LET Y1 = X**2
LET Y2 = X**(1/2)
LET Y3 = MAX(Y1,Y2)
PRINT Y1 Y2 Y3
