Matlab中的图像数据类型转换 MATLAB中读入图像的数据类型是uint8,而在矩阵中使用的数据类型是double因此 I2=im2double(I1) :把图像数组I1转换成double精度类型;如果不转换,在对uint8进行加减时会产生溢出,可能提示的错误为:Function '*' is not defined for values of class 'uint8'。 图像数据类型转换函数 默认...

• MATLAB有三十多个工具箱大致可分为两类:功能型工具箱和领域型工具箱.$ B; `: L2 v, Q/ B4 Z" o 功能型工具箱主要用来扩充MATLAB的符号计算功能、图形建模仿真功能、文字处理功能以及与硬件实时交互功能,能用于多种学科。而领域型工具箱是专业性很强的。如控制系统工具箱(Control System Toolbox)、信号...
The limitmode can have either of two values: "auto"— Enable automatic limit selection. MATLAB selects the limits based on the range of your data and the value of the YLimitMethod property of the axes. If you plot into the axes multiple times, the limits update to encompass all the ...

we will need to run the functionL=real(L);on the vector L.Then, we will sort the entries of L using the MATLAB commandL=sort(L);To output vector L correctly, you will go through two more steps:(1) In your code, you will need to ensure that the multiple eigenvalues show as the...
