calCalcInput

calCalcInput(
l_keywords
[ t_expression ]
)
=> t / nil

Manipulates Buffer and Stack contents and enters arbitrary expressions into Buffer.

l_keywords	Integer, symbol, or list of symbols indicating the keywords whose corresponding function is to be performed on the contents of Buffer or Stack.
t_expression	Expression to be copied to Buffer content.

`t`	The command executes successfully.
`nil`	Indicates an error.

The following example opens Calculator.

calCalculatorFormCB()

=> t

Note that the Buffer is currently empty.

The following example copies the expression "expr(x sin(x) linRg(-12.5 15.5 0.5))" in Buffer.

calCalcInput("expression" "expr(x sin(x) linRg(-12.5 15.5 0.5))")

=> calSetBuffer("expr(x sin(x) linRg(-12.5 15.5 0.5))")

=> t

=> t

Click plot or the Evaluate the Buffer icon to evaluate the expression in Buffer.

The resultant waveform is plotted in a Waveform window.

The following example clears the contents of Buffer.

calCalcInput("clear")

calSetBuffer("")

=> t

=> t

The following example places the expression "1+2" in Buffer.

calCalcInput("expression" "1+2")

calSetBuffer("1+2")

=> t

=> t

The following expression is created in Buffer.

The following example applies the function on the contents of Buffer in the order their corresponding keywords are specified.

calCalcInput(list("exp" "square" "ln"))

=> calSetBuffer("exp(1+2)")

=> t

=> calSetBuffer("exp(1+2)**2")

=> t

=> calSetBuffer("ln(exp(1+2)**2)")

=> t

=> t

The final expression created in Buffer is shown, as follows:

If you evaluate this expression manually, the result is 6.

Click plot or the Evaluate the Buffer icon to evaluate the expression in the Buffer.

The resultant scalar value 6 is displayed in Buffer, as follows.
