Example: Convert this system to a matrix:

X – Y = 0

2X + Y = 5

Command: SYST2MAT([X-Y, 2*X+Y=5],[X, Y])

 

1 –1 0

 

Result:

 

2 1 –5

 

 

 

 

 

 

%T

 

 

 

 

Type:

Function

 

Description:

Percent of Total Function: Returns the percent of the first argument that is represented by the

 

second argument.

 

 

If both arguments are unit objects, the units must be consistent with each other.

 

The dimensions of a unit object are dropped from the result, but units are part of the calculation.

 

For more information on using temperature units with arithmetic functions, refer to the entry for

 

+.

Example 1:

1_m 500

_cm %T returns 500, because 500 cm represents 500% of 1 m.

Example 2:

100_K 50_K %T returns 50.

TABVAL

Type:

Command

Description:

For an expression and a list of values, stores the expression in EQ, and returns the results of

 

substituting the values for the current variable in the expression.

Access:

PGRAPH L, !ÖGRAPHL

Input:

Level 2/Argument 1: An algebraic expression in terms of the current variable.

 

Level 1/Argument 2: A list of values for which the expression is to be evaluated.

Output: Level 2/Item 1: The algebraic expression.

Level 1/Item 2: A list containing two lists: a list of the values and a list of the corresponding results.

Flags: Exact mode must be set (flag –105 clear). Numeric mode must not be set (flag –3 clear).

Example: Substitute 1, 2, and 3 into x2 + 1 . Command: TABVAL(X^2+1,{1, 2, 3})
