Why do I receive the error that arrays have incompatible sizes for this operation?

When the code runs the error message reads:
- Arrays have incompatible sizes for this operation
- Error in line 5
- D=A:(A-C)/B:C;
clear all
A=('initial value:');
B=('number of values:');
C=('final value:');
D=A:(A-C)/B:C;
E=3412.14.*D;
F=(3412.14/2544.5).*D;
G=550.*D;
table(D',E',F',G','VariableNames',{'D','E','F','G'})

try this:
A=input('initial value:');
B=input('number of values:');
C=input('final value:');
% A=2;
% B=10;
% C=20;
D=A:(C-A)/B:C;
E=3412.14.*D;
F=(3412.14/2544.5).*D;
G=550.*D;
table(D',E',F',G','VariableNames',{'D','E','F','G'})

A=2;
B=10;
C=20;
D=A:(A-C)/B:C;
E=3412.14.*D;
F=(3412.14/2544.5).*D;
G=550.*D;
table(D',E',F',G','VariableNames',{'D','E','F','G'})
whenever "final value-initial value"
A=2;
B=10;
C=20;
D=A:(C-A)/B:C;
E=3412.14.*D;
F=(3412.14/2544.5).*D;
G=550.*D;
table(D',E',F',G','VariableNames',{'D','E','F','G'})

I guess those first three lines are supposed to be calls to input()
A=('initial value:');
B=('number of values:');
C=('final value:');
whos()
D=A:(A-C)/B:C;
As in:
A=input('initial value:');
B=input('number of values:');
C=input('final value:');
D=A:(A-C)/B:C;

Also, note that this:
D=A:(C-A)/B:C;
gives you one more element than was requested:
A = 0; % initial value
B = 10; % number of values
C = 1; % final value
D=A:(C-A)/B:C;
numel(D)
It's better to use linspace():
D = linspace(A,C,B);
numel(D)

B=imread('LOGO.bmp');
subplot(2,2,3),imshow(B),title('Watermark Image');
Wd=im2double(B);
DCTw=dct(Wd);
subplot(2,2,4),imshow(DCTw),title('DCT of Watermark Image');
DCTwi=(DCTw/2)+(DCTi/0.001);
WI=idct(DCTwi);
Arrays have incompatible sizes for this operation.

The error means what it says. The arrays are not compatible sizes. So what size are they? Nobody knows what LOGO.bmp is, so nobody knows what size DCTw is. Similarly, nobody knows what size DCTi is or where it came from. You are the only person with access to that information.
Check the sizes of your arrays. If they came from the same source, one may have been subject to some operation (e.g. padding or differencing) which has altered its size.
