Some of those applications come from MathWorks - you get them automatically with Toolboxes that you have installed. It is the place you go to run interactive MATLAB applications. The last of the global tabs is the Apps tab, shown below. This is an example of how the toolstrip uses context to direct you to the best options. The gallery is smart, only showing plots that are appropriate for the data that you've selected.

The downward facing arrow on the far right brings down the full extent of the plot gallery with many more choices. To create a plot from the gallery, you select the variables in the workspace that you want to plot and then select the type of visualization you want to use for that data. The Plots tab displays a gallery of plots available in MATLAB and any toolboxes that you have installed. The Plots tab, shown below, is where you go to create MATLAB Plots. The Home tab, shown above, is where you go to do general purpose operations like creating new files, importing data, managing your workspace, and setting your Desktop layout. For that reason, they are called global tabs. These three tabs are always there no matter what you are doing in MATLAB. When you open R2012b for the first time, you will notice three tabs - the Home tab, the Plots tab, and the Apps tab. We'll talk more about that in Part 2 of this series. You may have also noticed the light blue bar in the upper right corner. The File section has controls to do file related operations including creating scripts ( New Script), opening files ( Open), and comparing two files ( Compare).

For example, the picture below shows the Home tab with sections for operations on Files, Variables, Code and so forth. The controls are buttons, drop-down menus and other user interface elements that you use to do things in MATLAB.

Tabs are divided into sections that contain a series of related controls. The Toolstrip organizes MATLAB functionality in a series of tabs. In this first post, I will focus on the Toolstrip and introduce some important concepts. The Toolstrip reorganizes the Desktop functions found in the menus and toolbars from previous versions of MATLAB. The most notable change is the introduction of the MATLAB Toolstrip. For those who haven't installed R2012b yet, here is a picture of the new Desktop: Next up - Part 2: Customizing the R2012b MATLAB Desktopīy now many of you have downloaded and installed MATLAB R2012b and have noticed some big changes to the appearance and organization of the MATLAB Desktop.Have you discovered any new MATLAB functionality?.We demonstrate, using signal-to-noise ratio and correlation indicators, that the technique used is superior to the wavelet and moving average filter and outperforms the proposed denoising NIRS signal. This is done subsequently to the signal pre-processing by reducing data dimension using the FASTICA method. It consists of adaptively modifying the wavelet coefficients based on the degree of noise contamination of the processed NIRS signal. Multi-resolution wavelet and PCA was applied successfully to enhance the NIRS signals.
Meanwhile, electronic components generate high frequency noise. NIRS signals include many types of noise, spread across a broad spectrum of frequencies, such as: low frequency noise from respiratory interference, 0.1 - 0.3 Hz, Mayer wave, about 0.1 Hz, cardiac interference, 0.8 - 2.0 Hz, and other artifacts from head and facial motions. This paper concerns usefulness of the NIRS signals denoising using the Hemodynamic Evoked Response (HomER) as graphical user interface displays the NIRS data, fast independent component analysis (FASTICA) method to reduce data dimension and the combined Wavelet & PCA method for enhancing NIRS signals.
