Hi There, I'm trying to output data to screen in two columns, the first column contains the ginputs (x,y coordinates) from user point selections using the mouse, whilst the second column is a set of reference coordinates held in the string "ActualValues".
I've only got 3 ginput (x,y) values in contrast to 10 reference values as I'm still getting the code functional.
I know this is a very basic problem, but I'm stuck fast and would really appreciate some help!
I keep getting the following error: Error using vertcat Dimensions of matrices being concatenated are not consistent. FinalOutput = [A, ActualValues; B; C];
This is my code:
clear
clc
close all
Map=imread('Map.Jpg');
imshow(Map);
hold on;
A = zeros(1, 24);
B = zeros(1, 24);
C = zeros(1, 24);
ActualValues = [124 93 109 77 125 83 117 75 122 80];
uiwait(msgbox('Choose Point A'));
[x,y] = ginput(1);
hline = plot(x,y,'r+', 'MarkerSize', 50);
A = [x, y];
uiwait(msgbox('Choose Point B'));
delete(hline);
[x,y] = ginput(1);
hline1 = plot(x,y,'r+', 'MarkerSize', 50);
B = [x, y];
uiwait(msgbox('Choose Point C'));
delete(hline1);
[x,y] = ginput(1);
hline2 = plot(x,y,'r+', 'MarkerSize', 50);
C = [x, y];
%Display Values:
disp ( 'User Values: Actual Values: Error:')
%FinalOutput = [A, B, C]; Formats output
%disp(FinalOutput); Displays previous formatted output (outputs FinalOutput)
FinalOutput = [A, ActualValues; B; C];
disp(FinalOutput);
disp(A);
disp(B);
disp(C);
How do I Fix this?
Many thanks.

ActualValues = [124 93 109 77 125 83 117 75 122 80];
this should be a matrix with..it shall have both x and y coordinates.

I've tried that it still doesn't work, originally it was: ActualValues = [124 93; 109 77; 125 83; 117 75; 122 80];
its something to do with how its referenced in "finalOutput" at the bottom, but I don't know what or indeed how to correct, please help!
FinalOutput = [A, ActualValues; B; C]; disp(FinalOutput);

USe this:
FinalOutput = [A; ActualValues; B; C]
with ActualValues as [124 93; 109 77; 125 83; 117 75; 122 80];

A= [2, 3]
B= [4, 7]
C= [1, 8]
D= [1 1; 2 2; 3 3; 4 4; 5 5; 6 6; 7 7]
FinalOutput = [A; D; B; C]
is it repeating?

I'm sorry, I didn't get a response, so I posted out a wider question!
Looks Like I'm repeating myself too!
The amendment to the code you provided repeats as you can see above, I'd like the first, 7th and 8th x, y coords in the first column and the other values in the column next to it.
I appreciate your help!
