Error using horzcat Dimensions of matrices being concatenated are not consistent.

I can't arrange my data as the error shows like this:

Error using horzcat.

Dimensions of matrices being concatenated are not consistent.

Error in DemoCircle (line 29)

TotalC = [y0, x0, listC]

I need help. This is my coding:

count(i) = sum(((x-x0(i)).^2+(y-y0(i)).^2<=R^2));

listC = count.'

TotalC = [y0, x0, listC]

y0 & x0 both value are 7125x1 double. same goes to listC. The problem is that when I run the coding with TotalC = [y0, x0, listC] ..The error shows as above.

Hope someone can help this

size(x0)
size(y0)
size(listC)

[hanif hamden]

all have the same size

7125 x 1

Use the debugger to solve such problems. Type in the command window:

dbstop if error

Start the code again, and when the problem let Matlab stop, check the sizes of the used arrays:

size(x0)
size(y0)
size(listC)

I guess you want:

listC = count;

without transposing.

[hanif hamden]

all the sizes are the same

7125 x 1 ..

transposing the count bcause i want to get the same size with the x0 and y0

[madhan ravi]

Try:

TotalC = [y0(:), x0(:), listC(:)]

@hanif hamden: If all 3 variables have the size [7125 x 1], the vertical concatenation would work successfully. Please check this again.

yeah there some error from the data. I just fixed it then it works well. Thank you so much :)
