The MATLAB System Block 1

Posted by Guy Rouleau,

The MATLAB System Block In R2013b, you will notice a new block in the Simulink Library Browser: The MATLAB System block. System Object Before looking at the MATLAB System block, let's looks at the evolution of System objects. In R2010a, System objects were introduced in the Signal Processing Blockset. In contrast to MATLAB functions, System objects are... read more >>

A scope for Simulink and MATLAB

Posted by Guy Rouleau,

A scope for Simulink and MATLAB Do you know about the Time Scope available with the DSP System Toolbox? This visualization tool was introduced in release R2010a and has been improved upon every release thereafter. The novelty of this tool is that it ships as both a Simulink block and a System object (dsp.TimeScope) and therefore offers the... read more >>

Frames… from signals to blocks 5

Posted by Guy Rouleau,

Frames… from signals to blocks Today I want to talk about an important topic for DSP System Toolbox and Communication System Toolbox users: Frame-Based Processing Beginning in R2010b, MathWorks started to significantly change the handling of frame- and sample-based processing. Currently, we are in a transition phase and it's time to update your models to the... read more >>

Mixed-signal modeling with Simulink 11

Posted by Guy Rouleau,

Mixed-signal modeling with Simulink If you’re a mixed-signal engineer, we have a Christmas present for you – a new library of mixed-signal blocks and demos available for free. My colleague Mike Woodward explains all. Designing mixed-signal systems with the free mixed-signal library For years now, MathWorks engineers have been building mixed-signal examples for customers. We’ve built... read more >>

Introducing the System Toolboxes 5

Posted by Guy Rouleau,

Introducing the System Toolboxes This week I am teaming up with my colleague Ken Karnofsky to introduce another big change in MATLAB R2011a. Guy: So Ken, what is this big change? Ken: In MATLAB R2011a, not only the code generation products changed. The products for designing signal processing algorithms have also been reorganized. Here is... read more >>

Radar Tracking in Simulink: Variable Size Signals 10

Posted by Seth Popinchalk,

Radar Tracking in Simulink: Variable Size Signals This week I welcome guest blogger Aarti Ramani to talk about a long requested feature, variable size signals in Simulink. Depending on target ranges, radar systems operate in different modes (different lengths of data etc).  Let’s assume we have two planes at two different altitudes. Now, what happens if there is a new... read more >>

MathWorks Conversations and the FFT 10

Posted by Seth Popinchalk,

MathWorks Conversations and the FFT If you are like me, you read the doc, a lot.  I am often clicking on the help just to verify my understanding of a function’s syntax, or the behavior of a block.  That is why I wasn’t surprised to find myself involved in a detailed discussion about the documentation for FFT.  You... read more >>
