I have 2 matrices that look like this
2016_Subject_
2016_Subject_
2016_Subject_
_01
_02
_03
and I need to put the word 'Speed' in between each line - Expected answer is
2016_Subject_Speed_01
2016_Subject_Speed_02
2016_Subject_Speed_03
this code
[L(i,1:end-2), 'Speed', L(i,end-2:end),]
where L is ls(targetfolder) ie. a list of the subfolders in a main folder and looks like
2016_Subject_01
2016_Subject_02
2016_Subject_03
doesn't work and comes up with the error
"Error using horzcat Dimensions of matrices being concatenated are not consistent."
which is only due to the inclusion of the words.
Any ideas how to overcome this?
Thanks in advance

You can post the expected result, because "put the word 'Speed' in between each line" is not clear

@Eleanor H: it is still not very clear exactly how your data are stored, but you can try experimenting with strcat to achieve what you want:
A = {...
'2016_Subject_'
'2016_Subject_'
'2016_Subject_'};
B = {...
'_01'
'_02'
'_03'};
strcat(A,'Speed',B)
creates this:
ans =
'2016_Subject_Speed_01 '
'2016_Subject_Speed_02'
'2016_Subject_Speed_03'

Use strcat
L1 = ['2016_Subject_'; '2016_Subject_'; '2016_Subject_']
L2 = ['_01'; '_02'; '_03'];
strcat(L1, 'Speed', L2)
It also works with cells
C1 = {'1_Subject_'; '10_Subject_'; '1000_Subject_'};
C2 = {'_01'; '_02'; '_1000'};
strcat(C1, 'Speed', C2)

a = repmat('2016_Subject_',3,1);
b = ['_01'; '_02'; '_03'];
your_array = cat(2,a,repmat('Speed',size(a,1),1),b);
