Insert numeric values (rx1 matrix) inside a cell

Hi. I would like to insert a column of 100:
rep = repmat(100,157,1);
inside the first cell (see image) so that 157x2 becomes 157x3.
The third column represents "rep".
How can I do this?

a=randi(100,157,2);
b=randi(200,189,2);
c=randi(300,183,2);
mat={a;b;c} % making a cell array
mat = 3×1 cell array
{157×2 double} {189×2 double} {183×2 double}
% rep = repmat(100,157,1);
mat3={[mat{2,1} repmat(100,size(mat{2,1},1),1)]};
for i=1:size(mat,1)
aaa(i)={[mat{i,1} repmat(100,size(mat{i,1},1),1)]};
end
output=aaa'
output = 3×1 cell array
{157×3 double} {189×3 double} {183×3 double}

Thank you for the answer. I don't want to insert the same value 100 to all cells.
At the first cell (157x2) I need to insert the third column of all 100.
At the second cell (189x2) I need to insert the third column of all 150.
At the third cell (183x2) I must insert the third column of all 200.
tyr this:
a=randi(100,157,2);
b=randi(200,189,2);
c=randi(300,183,2);
mat={a;b;c}; % making a cell array
% rep = repmat(100,157,1);
% mat3={[mat{2,1} repmat(100,size(mat{2,1},1),1)]};
for i=1:size(mat,1)
if i==1
aaa(i)={[mat{i,1} repmat(100,size(mat{i,1},1),1)]};
elseif i==2
aaa(i)={[mat{i,1} repmat(150,size(mat{i,1},1),1)]};
elseif i==3
aaa(i)={[mat{i,1} repmat(200,size(mat{i,1},1),1)]};
end
end
output=aaa';
