i do have GUI which solves P,EL,H, my problem if i got result in decimal values how do I interpolate the result? because my program can interpolate only whole numbers such as 700,701 but not on decimal values =(

a = get(handles.input1_gamma,'String'); %GAMMA
b = get(handles.input2_h,'String');    %H
c = get(handles.input3_q,'String');     %Q
d = get(handles.input4_power,'String');  %POWER
e = get(handles.input5_eout,'String');

out = str2num(b) + str2num(e);
set(handles.total_answer,'String',out);
 data = xlsread('table.xlsx')
     %b = strcat(PathName,F);
    [m n] = size(data)
    k = get(handles.total_answer,'String')
    for i = 1 : m 
        A = data(i); %check xa 1st row then compare value
        A = int2str(A);
        if A == k
        n = i;
        score = data(n,2)%compare sa 2nd value
        clc; %clear and cmd
        set(handles.equalel,'String',score);
        break;
     else 
            mHeight = [700 750 800];
            mEout = [100 200 300];
            mElevation = out;
            outputArea = interp1(mHeight, mEout, mElevation);
            set(handles.equalel,'String',outputArea);

          end
      end

interp1 has no problems interpolating decimal numbers.

Comparing values by comparing their strings is... unusual. And you should not use == to compare strings: use strcmp() or equal() in case the two are different length.

okie thanks a lot.. i got how to use strcmp..

if ever the two table are different length how to use interp with that sir?
