I am trying to see if a column in a cell has string matching to what I stipulate.

I have read info on cells and still can not understand how to get this to return an answer.

The cell has integers 1:4 for the first column, then strings for the next column, then numerical values for rows 3 and 4.

I.e.

Point_list=

{'Point',1,2,3,4;'Type','Fixed','Unfixed','Unfixed','Unfixed';'X',800.000,120.000,2400.000,7210.000;'Y',60.000,700.000,1630.000,6320.000}

What I am trying to achieve:

If the string states 'Fixed' then return value 7

else return value 15.

Code I am using:

v(1,1) = zeros

if Points_list {:,2} strcmp(:,'Fixed')

v(1,1) = 7

else

    v(1,1) = 15
end

What is the easiest way to get what I would like?

Thanks.

one way to do this is :

% create the cell data
Point_list={'Point',1,2,3,4;'Type','Fixed','Unfixed','Unfixed','Unfixed';'X',800.000,120.000,2400.000,7210.000;'Y',60.000,700.000,1630.000,6320.000};
% initialize all value to 7
ValueFixedUnfixed = 7*ones(1,size(Point_list,2)-1); 
% compare 2nd row from 2nd col until end with string Unfixed and change corresponding value to 15 in the variable ValueFixedUnfixed
ValueFixedUnfixed(strcmp(Point_list(2,2:end),'Unfixed')) = 15; 
% display to confirm
disp(Point_list(2,2:end))
disp(ValueFixedUnfixed)
