What is the way to get only the desired part of the text?

Hello, I'm a student learning matlab on my own.

Please understand even if I don't understand the contents of the question because I lack knowledge.

It's a question.

What is the way to get only the desired part of the text?

For example

text =

Name: ABC

Age: 20

Gender: Male

Height: 180cm.

Weight: 75.

If there's a text file like this,

I'm going to store the information 20 and 180 I need in the variable 'age, height', respectively.

I'm going to use the function "extract After,

age = extractAfter(text,'age : ')

height = extractAfter(text,'height : ')

If I write the code like this, the result I want will not come out.

Can you tell me another way?

Take a look at the split and splitlines functions.

https://www.mathworks.com/help/matlab/ref/splitlines.html

text = ['Name: ABC' newline 'Age: 20' newline 'Gender: Male' newline 'Height: 180cm.' newline 'Weight: 75.']

text = 
    'Name: ABC
     Age: 20
     Gender: Male
     Height: 180cm.
     Weight: 75.'

splitlines(text)

ans = 5×1 cell array
    {'Name: ABC'     }
    {'Age: 20'       }
    {'Gender: Male'  }
    {'Height: 180cm.'}
    {'Weight: 75.'   }

split(text)

ans = 10×1 cell array
    {'Name:'  }
    {'ABC'    }
    {'Age:'   }
    {'20'     }
    {'Gender:'}
    {'Male'   }
    {'Height:'}
    {'180cm.' }
    {'Weight:'}
    {'75.'    }

txt = fileread('test.txt');
tkn = regexp(txt,'^(\w+):\s+(\d*\.?\d*)(\S*)','tokens','lineanchors');
tkn = vertcat(tkn{:})

tkn = 5×3 cell array
    {'Name'  }    {0×0 char}    {'ABC'   }
    {'Age'   }    {'20'    }    {0×0 char}
    {'Gender'}    {0×0 char}    {'Male'  }
    {'Height'}    {'180'   }    {'cm.'   }
    {'Weight'}    {'75.'   }    {0×0 char}

vec = str2double(tkn(:,2))

vec = 5×1

NaN 20 NaN 180 75
