空数组(empty array):没有元素的数组 标量(scalar):是指1 × 1 1\times11×1的矩阵,即为只含一个数的矩阵 向量(vector):是指1 × n 1\times n1×n或n × 1 n\times 1n×1的矩阵,即为只有一行或一列的矩阵 矩阵(matrix):是一个矩形的m × n m\times nm×n数组,即二维数组 ...
To append text to strings, use the plus operator or the strcat function. For example, if you concatenate two strings, then the result is a 1-by-2 string array. str = ["Hello" "World"] str = 1×2 string array "Hello" "World" However, if you concatenate two character vectors, ...
