Same number of columns, but getting "Dimensions of arrays being concatenated are not consistent" error

The two arrays I'm trying to concatenate are both of column size 1, so why am I unable to horzcat them?

Hi Liam,

Your two arrays should have the same number of rows when you use horzcat.

d=[1;2;3;4;5;6;7];
f=[3;4;5;6;7;8;9];
horzcat(d,f)

Here is another example where f and d have different no. of columns but same no. of rows

f=[4 5;4 5;6 7;7 8;3 2;3 4;6 7];
d=[1;2;3;4;5;6;7];
horzcat(d,f)

Waseem,

So if i was trying to run this code:

coeff=corrcoef([y,y1]);

How would I go about it?

y is 256x1 and y1 is 22x1.

Is it fine if we use vertcat?

y=ones(256,1);
y1=zeros(22,1);
[y;y1]; % or vertcat(y,y1);
