Finding a specific row in a matrix based on user inputs?

I have a matrix with 365 rows and 7 columns, the first column is the month (1-12) and the second column is a day of that month. The user inputs what month they want to look at in a numeric value (1-12) and then the day they want (1-31), but then I need to take that input data and only find the array with those two specific values, I have no clue how to copy just that row based on those two inputs.

#Do the necessary changes, as required

%let say mat_data is the main matrix 
mat_data=[1 1 3 4 56
          1 2 3 4 50
          1 3 4 5 90
          2 3 5 6 70];
month=input('Enter the Month Any value 1-12: ');
day=input('Enter the Day Any value 1-31: ');
disp('The details is ');
mat_data(mat_data(:,1)==month & mat_data(:,2)==day,:)

Why to use find when we have logical indexing at best?

Yes, thanks for pointing it out

Let A be your matrix of size 365*7.

themonths = A(:,1) ; 
thedays = A(:,2) ; 
% Let us say I want 7th month and 7th day indices 
m = 7 ; d = 7 ; 
idx = themonths == m && thedays == d ; 
iwant = A(idx,:) ;
