Mix C and matlab in Linux and mix linuxmatlab1 Overview 1.1 Introduction to Matlab
MATLAB is a commercial mathematical software developed by MathWorks. It is used for algorithm development, data visualization, data analysis, and numerical computing. It is a high-level computing language and interactive environment. It consists of two parts:

Because FRR and far conflict with each other, the probability of equal error rate is equal when the two are equal. When the threshold is th, the corresponding FRR has a value and far has a value. In this way, a group of corresponding FRR and far are obtained. The far is used as the horizontal coordinate, and the FRR is used as the vertical coordinate to draw the curve, that is, the ROC curve. Then draw the Y = x curve. When the two curves intersect, th

Some time ago to explore the Java invoke matlab things, do not say how deep the study, also counted the results, to achieve the purpose. The Java program is also used to invoke functions in MATLAB.
In order to say it, the beginning must be the next MATLAB to see. Which one is next. Starting with the next 7.0 feels very new. Later I thought it was not, and now th

Borland C++builder is a novel visual programming language. In the engineering application, we generally use the C++builder language to write the application, realizes the interactive interface, the data acquisition and the port operation and so on, but c++builder in the numerical processing analysis and the algorithm tool and so on aspect, its efficiency is far lower than MATLAB language. In the accurate and convenient rendering of data graphics,

Use of MATLAB Compiler (compiler) or MCC-- Personally think it is the right way
1. Set the Compiler:
