i have 2 data:

1. Dummy Data for position and condition of sea)

X(latitude)  Y(longitude)  Z(height)
10000    10010   -11
10010   10010   -13
10020   10010   -10
10030   10010   -9
10040   10010   -14
10050   10010   -17
10060   10010   -11
10070   10010   -14
10080   10010   -17
10090   10010   -8
10100   10010   -7
10000   10020   -15
10010   10020   -8
10020   10020   -9
10030   10020   -10
10040   10020   -11
10050   10020   -14
10060   10020   -8
10070   10020   -7
10080   10020   -6
10090   10020   -6
10100   10020   -8
10000   10030   -9
10010   10030   -10
10020   10030   -11
10030   10030   -14
10040   10030   -11
10050   10030   -12
10060   10030   -14
10070   10030   -9
10080   10030   -10
10090   10030   -12
10100   10030   -14

2. Tidal Data for 03/03/15

ETA(time)  Tidal Height
0000    2.2
0100    2.2
0200    2.0
0300    1.6
0400    1.3
0500    1.0
0600    0.8
0700    0.7
0800    0.9
0900    1.3
1000    1.7
1100    2.0
1200    2.1
1300    2.2
1400    2.1
1500    1.8
1600    1.5
1700    1.2
1800    1.0
1900    1.0
2000    1.1
2100    1.5
2200    1.9
2300    2.2

Then, my problems are:

how i can run this coding?

%D = x(latitude),y(longitude) and z(heighting) data
D =load('database.m');

%detail input char
S = input('Name of Ship :\n' , 's')
C = input('Name of Captain :\n' , 's')

%detail input data(ddmmyy) will be load tide data
T = input ('Date (ddmmyy):\n' , 's')
%if user input 030315, the data (tide030315.m) will be load

%detail input int
V = input('Draft Vessel (m):\n' , 's')
E = input('ETA (hhmm):\n' , 's')
U = input('UKC (m):\n' , 's')
P = input(Current position (X/Y) :\n' , 's') %posituion vessel during emergency

%(user input ETA [eg: 1200, then the value 2.1 will be used in algorithm)
% how I can use if/else function from the tidal data when captain choose 1200,then value 2.1 will be use in algorithm below

%algorithm
HS(x,y,z)= T(z) - D(x,y,z);
UKC(x,y,z)= HS(x,y,z) - V(z);

%how looping function can be used with above algorithm

%condition: UKC(x,y,z)=> U

%best point(x,y) will be show from the current position of vessel which input by captain.

[Walter Roberson]

Assuming that your tidal data is stored in the variable "tidal" whose first column is ETA and whose second column is tide height, then to find the tide height for given time "eta", use

estimated_tide = interp1(tidal(:,1), tidal(:,2), eta);
