Mathematical Functions
The mathematical functions that can be performed by the LC1-USB allow the user
open-ended capabilities. In the previous section, the example used subtraction to
take out the background, or dark noise, from the signal. Complex functions may be
entered and executed on any given layer except the input layer. Squaring a layer can
be achieved by multiplying the layer by itself, which can act to intensify the spectral
information. Information from locked layers can be mathematically compared to
active layers. The symbols, + - * /, as well as levels of parentheses, can be used.
Note:
When using predefined functions like PEAKS(), SMOOTH(), etc., the syntax does not
allow the use of mathematical functions. This can easily be bypassed. By using the
predefined function on a layer, a math function can be performed on a newly created
layer.

3D View
When working with multiple
layers, it is often convenient to
be able to see all of them
separately. In the example of
the Peak Finder function, there
were a total of four layers being
displayed. One way to see the
layers is to turn all of them off
except the one of interest.
However, other important information may be overlooked. Displaying all the layers
simultaneously can be confusing as can be seen below:
To better see the two separate layers, the plot window can
be shifted into 3D mode. To do this, move the cursor to the
origin where there is a small red square. Note that the
cursor changes from to . At this point, hold down the
left mouse button and move the cursor toward the center of
the plot window. This will cause the plot to fold out in 3D.
