whether you can add only new drawing objects or overwrite existing drawing objects in the current axis. Use hold on to preserve the current shape's property values from the current axis, and the graphics command that follows can only add graphics to the currently existing axis. However, when the data range of the new shape exceeds the range of the current axis, the command automatically changes the range of the axis to fit the new shape. Hold off before drawing a new drawing, reset the axis pro

You should put the file in the Matlabroot/toolbox path, if so, this problem, it is because of MATLAB to improve the start-up and speed of the adoption of an optimization measures. MATLAB Toolbox The functions under the cache for a while, only need to update the Toolboxcache on it. Method: Select File > Preferences > General. The General Preferences pane is displayed. Click Update Toolbox Path Cache and

MATLAB Image Processing _ directly operate on the pixel for color conversion, matlab Image Processing Requirement Directly operate the pixels of the RGB image and perform color-related operations. To master this, you must be familiar with matrix operations in MATLAB, especially the operations of the entire row and the entire column. For example: J = [1 2 3; 4 5 6

Mutual Conversion Between MATLAB Image Processing _ HSV and RGB color space, and MATLAB _ HSV The following code is a self-carried Conversion Function in matlab. It is posted here to facilitate future review and Study of Its Conversion Algorithm: HSV space: H (tone) -- S (saturation) -- V (brightness) Similar to the HSI color space: H (tone) -- S (saturation) --

To put it down, DLL is a dynamic link library and a binary library file and program interface after source code compilation. What is different from a static Link Library is, during compilation, the program does not link the execution body of the dynamic link library. Instead, it retains a call Mark in the file and loads the dynamic link library file into the memory only when the program is running. In addition, the DLL is shared during runtime, that is, when multiple programs are called, only on

(1) margin function: Calculate amplitude margin and phase angle margin and corresponding turning frequency Margin (mag,phase,w): The amplitude of mag (not in db), phase angle phase, and angular frequency w vectors obtained by the bode instruction are plotted with a bode graph with headroom and corresponding frequency display. Margin (Num,den): Calculates the amplitude margin and phase angle margin of the continuous system transfer function representation and plots the corresponding baud plot. S

You can speed up execution by using a long function in C language and compiling the MEX function. MATLAB itself is not with C language compiler, so require your machine has been installed VC,BC or watcom C. If you have set up the compiler in the installation of MATLAB, you should now be able to use the MEX command to compile the C language program. If there is no election, in the

The MATLAB help document provides two methods: Print function and getframe imwrite function. I think print is more convenient. Method 1: X = getframe (GCF); Method 2: Set (GCF, 'paperpositionmode', 'manual') % ensures that the saved image does not change with the screen window, consistent with the print Settings If there are many figure files, you

MATLAB provides various functions to display 3D images. Some functions can draw lines in 3D space, while others can draw curves and grid frames. In addition, colors can be used to represent the four-dimensional dimension. When a color is used in this way, it is called pseudocolor because it no longer shows the natural attribute of information as in the photo-color, and it is not the internal attribute of basic data. To simplify the discussion of 3D im
