c = strread(a)

c = strread(a, '', n)

c = strread(a, '', option, optionvalue)

c = strread(a, '', n, option, optionvalue)

[c1, c2, ...] = strread(a, format)

[c1, c2, ...] = strread(a, format, n)

[c1, c2, ...] = strread(a, format, option, optionvalue)

[c1, c2, ...] = strread(a, format, n, option, optionvalue)

'delimiter' Treats optionvalue as a new delimiter character.
'expchars' Treats optionvalue as a new exponent character. The default optionvalue is 'e', 'E'.
'whitespace' Treats each character in optionvalue as a new white space character. If optionvalue includes a backslash ('\'), the character after the backslash can be only 'n', 'r', 't', or '\'.
