How to convert char into double?

Hello everyone,

I have following char: "2.311.592 /" And I want to convert it to double and leave numbers only, I have tried to use

new = str2double(val);

But the output was NaN, what would you recommend me to do?

Your character number got two points?

Which number do you expect as output?

@Jan Simon

I expect the whole number without dots and slashes, i.e. 2311592.

Thank you.

Str = '2.311.592 /';
Str(Str < '0' | Str > '9') = [];
Value = sscanf(Str, '%d');

I need the value 43.3414 only

str = 'v: 43.3414 m^3/kg';
a   = sscanf(str, 'v: %f')
