如果size(A) 与 size(B) 相同,则会串联这两个数组;否则显示一条警告并返回一个空数组。 if isequal(size(A),size(B)) C = [A; B]; else disp('A and B are not the same size.') C = []; end 输出结果为: A and B are not the same size. 比较字符向量 使用strcmp 比较字符向量。当字...

disp('x is not greater than 5');end ```在这个例子中，因为`x`大于5，所以会显示消息"x is greater than 5"。2.使用逻辑运算符：```matlab a = 10;b = 20;if a > b disp('a is greater than b');else if a < b disp('a is less than b');else disp('a and b are equal');end...

第一句有错，后面的倒没什么大问题：1、第2行中间的续行符（...）是多余的，会导致后面的部分被当作注释。删掉或者在续行符后面换行即可。2、第3行多了个左括号（(）。改成：[filename,pathname]=uigetfile(... {'*.bmp;*.jpg;*.png;*.jpeg','Image Files(*.bmp, *.jpg, *.png,...
x = 42;ifexist('myfunction.m','file') && (myfunction(x) >= pi) disp('Expressions are true')end The first part of the expression evaluates to false. Therefore, MATLAB does not need to evaluate the second part of the expression, which would result in an undefined function error. ...
