本文介绍了两种字符串比较函数：strcmp 和 strcmpi。strcmp 进行大小写敏感的字符串比较，而 strcmpi 则忽略大小写差异进行比较。这两种函数可以用于比较两个字符串或者字符串数组。

strcmp

Compare strings (case sensitive)
Syntax

TF = strcmp(string,string)
TF = strcmp(string,cellstr)
TF = strcmp(cellstr,cellstr)

Description

TF = strcmp(string,string) compares two strings for equality. The strings are considered to be equal if the size and content of each are the same. The function returns a scalar logical 1 for equality, or scalar logical 0 for inequality.

TF = strcmp(string,cellstr) compares a string with each element of a cell array of strings. The function returns a logical array the same size as the cellstr input in which logical 1 represents equality. The order of the input arguments is not important.

TF = strcmp(cellstr,cellstr) compares each element of one cell array of strings with the same element of the other. The function returns a logical array the same size as either cell array input.

strcmpi

Compare strings (case insensitive)
Syntax

TF = strcmpi(string,string)
TF = strcmpi(string,cellstr)
TF = strcmpi(cellstr,cellstr)

Description

TF = strcmpi(string,string) compares two strings for equality, ignoring any differences in letter case. The strings are considered to be equal if the size and content of each are the same. The function returns a scalar logical 1 for equality, or scalar logical 0 for inequality.

TF = strcmpi(string,cellstr) compares a string with each element of a cell array of strings, ignoring letter case. The function returns a logical array the same size as the cellstr input in which logical 1 represents equality. The order of the input arguments is not important.

TF = strcmpi(cellstr,cellstr) compares each element of one cell array of strings with the same element of the other, ignoring letter case. The function returns a logical array the same size as the input arrays.
