matlab字符串能否运算

是的，Matlab中的字符串可以进行运算。可以使用eval函数将字符串转换为可执行的表达式。例如，可以将一个字符串定义为平方根运算，然后使用eval函数计算1到10的平方根。示例代码如下：

t = 'sqrt(i)';
for i = 1:10
    s(i) = {char(['The square root of ', int2str(i), ' is ', num2str(eval(t))])};
end
s(:)

输出结果为：

ans = 

  10×1 cell 数组

    {'The square root of 1 is 1'}
    {'The square root of 2 is 1.4142'}
    {'The square root of 3 is 1.7321'}
    {'The square root of 4 is 2'}
    {'The square root of 5 is 2.2361'}
    {'The square root of 6 is 2.4495'}
    {'The square root of 7 is 2.6458'}
    {'The square root of 8 is 2.8284'}
    {'The square root of 9 is 3'}
    {'The square root of 10 is 3.1623'}
