See if this is what you want. You can use linspace to make the 2 rows into 5 rows:
m = [...
6 1.256 1.365 0.358 2.589 2.365 2.365 2.456
8 3.250 3.255 3.62 1.25 1.256 2.321 3.214];
[rows, columns] = size(m);
m2 = zeros(rows + 3, columns);
for col = 1 : size(m, 2)
m2(:, col) = linspace(m(1, col), m(2, col), 5);
end
m2
m2 = 5×8
6.0000 1.2560 1.3650 0.3580 2.5890 2.3650 2.3650 2.4560 6.5000 1.7545 1.8375 1.1735 2.2542 2.0878 2.3540 2.6455 7.0000 2.2530 2.3100 1.9890 1.9195 1.8105 2.3430 2.8350 7.5000 2.7515 2.7825 2.8045 1.5848 1.5333 2.3320 3.0245 8.0000 3.2500 3.2550 3.6200 1.2500 1.2560 2.3210 3.2140

You need to have X and Y vector arrays. The X values need to incapsulate the requested points. You may use interp1 fucntion. For example:
X=[6 1.256 10 ];
Y=[8 3.250 8.5 ];
Ynew = interp1(X,Y,[6.5, 7, 7.5])
