strtod

Arguments

str

a character string or matrix of character strings.

d

a real or matrix of reals.

endstr

a character string or matrix of character strings (next character in str after the numerical value).

Description

[d, endstr] = strtod(str) parses strings str interpreting its content as a floating point number and returns its value as a real. If str does not contain any numerical value then d equals Nan.

Remark

This function is based on the strtod C function which causes different behaviors on Windows and Linux. In fact, on Windows, it is possible to use d or D for exponents, but it is not possible to use hexadecimal numbers.

Examples

strtod('123.556This is a sample real')
[d,endstr] = strtod('123.556This is a sample real')
strtod(['123.556This is a sample real','888.666 here'])
[d,endstr] =strtod(['123.556This is a sample real','888.666 here'])
