If you want to remove certain values from the array, please have a look at this simple example: v = randi(10,1,20)% generate 20 random integer numbers in interval 0 to 20 v =1×20 8 3 2 3 2 8 10 7 10 5 4 4 3 7 7
s =2×15 char array'0.538 -2.26' ' 1.83 0.862' Displaypias a floating-point number to a specified precision. formatSpec ='%.2f'; s = num2str(pi,formatSpec) s = '3.14' Input Arguments collapse all Input array, specified as a numeric array. ...
When the input argument is a string array, thedoublefunction treats each element as the representation of a floating-point value. However, when the input is a character array,doubleinstead converts each character to a number representing its Unicode® value. As an alternative, use thestr2double...

MATLAB R2012a安装教程 安装包链接 安装步骤 配置 license过期 更改系统时间 更改license文件 MATLAB是用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境。MATLAB功能十分强大,但属于商业软件,对于学生党并不十分友好。前几天正好帮朋友安装
Each variable must be a 2-Ddoublearray. The output includes only the real component of complex numbers. Thesavefunction writes data from each variable sequentially to the file. If you plan to use theloadfunction to read the file, all variables must have the same number of columns. Theload...
