extract numbers from cell array

hello!

i have this cell array wich may have many cells,and not only three as here.

A = {'jdldi'; 'jdks5.4555h'; 'f67'}

i want to extract only the numbers,and show them as one number

for this example i want the result to be 5.455567

any help please?

Thank you very much!

What about 67?

[alex]

in the first cell:no numbers

in the second cell:5.4555

in the third cell:67

so,i want to merge all the numbers from every cell and take the number 5.455567

A = {'jdldi'; 'jdks5.4555h'; 'f67'}
b=regexp(A,'\d+(\.)?(\d+)?','match')
out=str2double([b{:}])

A = {'jdldi'; 'jdks5.4555h'; 'f67'}
b=regexp(A,'\d+(\.)?(\d+)?','match')
out=strjoin([b{:}],'')

Answer 2

[Andrei Bobrov]

A1 = regexp(A,'[\d*\.]*\d*','match')
A2 = [A1{:}]
out = str2double(strcat(A2{:}))

Answer 3

A simple version:

A = {'jdldi'; 'jdks5.4555h'; 'f67'}
S = cat(2, A{:});
S(isletter(S)) = [];

The simpler the code, the less chances to insert a bug.

Thanks Jan! I wasn't aware of the isletter function
