MATLAB: Extract integers from random strings

integerscanstring

Hi,

I have many strings composed by letters and numbers. Every string has this format 'randomword.integer'. I'd like to ignore the first part (word) and get the second (number). The first part keep changing so i can't use:

a= 'randomword.integer'
int=sscanf(a,'randomword.%d')

Any help?

Thanks in advance

sscanf(a, '%*[^.].%d')

Similar to how you were doing it:

 ST=join("Hi " + num2str(A',"%1.12e"), newline )
ST = 
    "Hi 2.101000000000e-06
     Hi 2.255670000000e-07
     Hi 1.200041367890e+00
     Hi 6.600005235300e+01"

Or using sprintf like Walter suggested:

 >> sprintf('Hi %1.12e\n',A)
 ans =
    'Hi 2.101000000000e-06
     Hi 2.255670000000e-07
     Hi 1.200041367890e+00
     Hi 6.600005235300e+01
     '

Note that the first method returns a string without a trailing newline and sprintf returns a character vector with one.

Hi,

you are nearly there, I believe: suppose you write in your program at the top

myfilename = 'analysed_data1';

you just call save with

save(fullfile(path, myfilename));
