Matlab Array Manipulation
-
How to remove all elements greater than 5 from a vector.
myVector = [10 0 0 1 12 3 0 0 4 5 1 12 0 0];
%index contains indices of elements within myVector which are greater than 5
index = find(myVector > 5);
myVector(index) = []Alternatively, logical indexing can be used (and is more efficient)
myVector(myVector > 5) = [];
This is one of the "tricks" or methods to manipulate the arrays using Matlab.

Project Updates / Status
- Added newer field emitter models to study emission details
This is needed to understand different models and how each geometry affect emission
- Improved area calculation and current calculation.
Previous methods were slow and unreliable.
- Pre-allocation added for vectorization.
Optimization for fast computation.
- Fast transition voltage calculation.
Just added this code today. Determination of transition voltage was through graphical plots which are more error prone. A simpler and faster approach is used to compute transition voltage.
- Code cleanup
As above.
Wish List =)
Faster automated code testing
