Hey. This some pid code for the atmega88 that I once used to control a heater. It s purpose is pretty specific, and I only wrote it to work on the mega88, so the code itself won t be too useful. It is a good place to start if you re trying to use or Figure out pid though.

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in Figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function .

Matlab小問題 問: Matlab仿真中怎樣編輯Scope中的圖象??? 答: 實現(xiàn)的方法有以下的幾種: 1)PrintScreen,然后粘貼到Windows位圖編輯器,選擇圖像點擊右鍵,選擇“反色”即可; 2)在Scope中,它的參數(shù)設置的第二頁,有一個Save Data to Workplace,將它選中,然后在下面的方框 中指定變量名,然后用plot命令畫出; 3)直接在模型上再加一個,to Workplace模塊,也用plot畫出; 4) 等scope顯示出來圖像以后,在matlab上運行 set(0, ShowHiddenHandles , On ) set(gcf, menubar , Figure ) 這時候你會發(fā)現(xiàn)scope的工具欄的上面多了一行,點擊insert-axes,鼠標會變成十字形狀,然后再圖像的任意一處雙擊左鍵出現(xiàn)一個對話框PropertyEditor,選中style在窗口的右便會出現(xiàn)color,這時你就可以任意修改背景顏色了。 問: 怎樣進行S-function的編程和使用??? 答: S-function也就是System-function的縮寫。說得簡單,S-function就是用MATLAB所提供的模型不能完全滿足用戶,而提供給用戶自己編寫程序來滿足自己要求模型的接口。要了

map identification laquo yuan Problem description : the digital image processing of an image often expressed as a macute M pixel matrix. Each pixel value is 0 or 1. The value of 0 pixel image, said background, and the value of a pixel image, said a map of a million, usually called map million pixels. When a pixel in another pixels above, below, left or right, said that two adjacent pixels of the pixel. An image of the pixels belonging to the same map yuan, instead of adjacent pixels belonging to different map yuan. Figure yuan identification of problems is right for the given image pixel map marking yuan, making the same map billion yuan pixel map of the same markings and different map billion yuan pixel map of their marks are different.

北京大學ACM題 Here is a geometric problem. You have an angle and some squares in the first quadrant of the plane rectangular coordinates. The vertex of the angle is fixed on the origin O of the coordinates, and both of its radial lines are specified by the input. The sizes of the squares are also specified by the input, and the squares can shift vertically and horizontally. Now your job is to use the squares and the radial lines of the angle to enclose the maximum area, which excludes the area of the squares (see Figure 1). You should note that the edges of the squares must be parallel to the axes.

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a Figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge

300 km 傳輸線和功率補償仿真 The circuit below represents an equivalent power system feeding a 300 km transmission line. The line is compensated by a shunt inductor at its receiving end. A circuit breaker allows energizing and de-energizing of the line. To simplify matters, only one of the three phases is represented. The parameters shown in the Figure are typical of a 735 kV power system.
