MATLAB是一种高级的数值计算和科学编程语言,它提供了丰富的函数库和工具箱,用于数据分析、可视化、模拟和算法开发。在MATLAB中,可以使用IF语句来进行条件判断和控制流程。contains函数是MATLAB中的一个字符串函数,用于判断一个字符串是否包含另一个字符串。
if contains(str, 'hello') disp('The string contains "hello"'); else disp('The string does not contain "hello"'); end 9. 判断一个矩阵是否为正定矩阵 if all(eig(A) > 0) disp('A is a positive definite matrix'); else disp('A is not a positive definite matrix'); end 10. 判断一...

An expression is true when its result is nonempty and contains only nonzero elements (logical or real numeric). Otherwise, the expression is false. The elseif and else blocks are optional. The statements execute only if previous expressions in the if...end block are false. An if block can...

I would like to fill a specific region automatically with the color red in my plot, if that's region contains my target point. Any idea how to do that's ? Thank you in advance my code: clear all clc x = [1 3 4 3 1 0 1]; y = [0 0 2 4 4 ...
There is no MATLAB function that examines every level of a structure of structures, or nested structure, to determine if a field exists. The 'isfield' function examines only the top level of a nested structure. To determine if a field exists at any other level,...
aIf the name of the main function does not match the name of the file that contains it, MATLAB ignores the function name and uses the file name instead. Sometimes this occurs when you move a function from one file to another, but do not change the name of the function. 如果主函数的...
This is a bug in MATLAB 7.11 (R2010b). The only workaround is to clear the object of the class, which contains the object with the anonymous function property, before it goes out of scope. In the above example, the function 'test' should be de...
