Http://www.ilovematlab.cn/thread-23500-1-1.htmlObjective: To use MATLAB to read data from the database and draw an image. Compile the M file into a DLL for other software.
Platform: Windows Server 2003 64-bit + Oracle10g Database
Try 1. Maid (64bit) + vs2005
You can access the database and draw images normally. But it cannot be compiled into a DLL. The problem is that the vs2005 compiler cannot be found in MATLAB
4. Data-type mxarray operations
In the above Matlab Engine functions, all data types related to variables are mxarray. Mxarray and a large number of functions starting with Mx are widely used in Matlab Engine programs and matlab c math libraries. Mxarray is a complex data structure, which corresponds to the array in MATLAB
1. If you assign values to any predefined MATLAB variable, the default value of the variable will be overwritten by the new value "temporary" until the memory variable is cleared using the clear command.
2. an array operation requires that a black dot be added after the vector or matrix. This is the calculation of the corresponding position data of the vector or matrix, for example,. * B indicates that the elements in array a are multiplied by the e

Always wanted to learn the Mex interface function, but it was not used before, so no special care. This time because of running someone else's code, feel or make a matlab wrapper, this will be more convenient. But this involves a Mex mash-up and calls to OpenCV.
Thus, there are a lot of problems involved, including configuration problems, compilation problems, parameter transfer problems, and so on. However, once you can master him, you are equivalent
Permanent variables commonly used in MATLAB.Ans: The default variable name for the computed result.I j: basic imaginary Units.EPS: Floating point of the system (F10A9BG OHT):INF: Infinitely large, example 1/0Nan nan: Non-numeric (n Voyage a nmnb Xie)Pi: Pi N (n=3. 1415926.. )。Realmax: The maximum value that the system can represent.Realmin: The minimum value that the system can represent,Nargin: Number of input parameters for the function:Nargout: Most of the output of a function

MATLAB is a common tool. Quick learning and mastering of MATLAB makes sense for efficient completion of work. This article describes how to learn and use MATLAB based on personal experience. These methods have been proven by several people.
The basic syntax for learning
MATLAB is often used to process large data. Sometimes it may take several days or even longer to process some data. IfAlgorithmThe final way to increase the speed is to start with the hardware. In this era of parallel computing, Matlab also provides parallel computing functions and even GPU acceleration. MATLAB seems to support parallel computing in 2010a. It int

As with the previous article, the engine is also the way, but the configuration method is very different.
Configuration environment: vs2013 (64-bit) +matlab2013a (64-bit) +win8.1 (64-bit)
Install the path with MATLAB: C:\Program files\matlab\r2013a as an example
1. Add Reference:
One is the reference to add MWArray.dll, the path is: C:\Program files\matlab\r2013
There are many ways to read the. mat file in MATLAB using Python, and there are a lot of Chinese and foreign forums.Visible: Python reads and writes from the mat file to the H5py file package.Detailed Address: http://blog.csdn.net/u013630349/article/details/47090299However, when reading the Matlab file, often is not a layer. MAT is enough to solve the problem, the. mat file may be the stored cell (100*200)
Sort usage:
B = sort (A, dim) % rearrange the elements in a along the dim direction specified in matrix.
[B, IX] = sort (a); % Where IX is an array of sizes equal to size (, each column is the replacement position mark corresponding to the element of the column vector in column.

MATLAB is a simple solution.
You can use the following registration code:14-58204-39252-07634-11570-16849-09455-22809-05445-13616-29058-08276-06885-

The previous blog has already mentioned how to configure the environment, that is, how to invoke MATLAB-generated DLL files in ASP. This blog intends to make a note of how MATLAB and C # data types are converted. As the need increases, I will continue to add new types of conversions.(1) C # Two-dimensional array to Matlab matrixThis code is mainly to the C # two-
Matlab to the Modelsim simulation data processing is also through the file read and write implementation. That is, through the Verilog statement, a signal in the simulation process is written to the file, and then in MATLAB in the data of this file read out, you can be analyzed in MATLAB.A simple example is also given to illustrate the whole process.The following Verilog statement is implemented to write th

EndConnection struct or CELL ARRAY
The operations for connecting to a struct array or cell are similar to those for operating a common matrix.
For example, generate a 3x8 struct matrix S, each of which has the following fields: X, Y, and Z. Connect the second structure array S2.
Generate a 3-by-8 structure matrix s:
For k = 1:24
S (K) = struct ('x', 10 * k, 'y', 10 * k + 1, 'z', 10 * k + 2 );
End
S = reshape (s, 3, 8 );
