ı want to create a matrices for this indicated values. but ı confused about something that ı shown below. what if its one component is not given or there is nothing there, what can ı put there to make all matrices same size?

In this situation, the data is missing. Read the page Missing Data in MATLAB.

You can't leave an element empty, but you can fill it with a missing value. MATLAB will then place the appropriate value for the data type. Use the function missing.

double, single, duration, and calendarDuration convert missing to NaN
datetime converts missing to NaT
categorical converts missing to <undefined>
string converts missing to <missing>

Depends on what you're going to do with the data. Maybe you should just delete the row. Maybe you should set the missing values to 0 or nan. Maybe you want to call fillmissing(). Tell us what you think you should do once you hit that row of the table. What are you doing with all the other, valid rows in the table?

>> % For L/D = 1/2, the following vectors are introduced:
% the Sommerfeld number vector
S = [0.021 0.030 0.036 0.041 0.057 0.085 0.140 0.274 0.342 0.428 0.762 1.714];
>> % the corresponding vector for the minimum film thickness variable,h0/c
hoc = [0.08 0.10 0.11 0.12 0.15 0.195 0.26 0.37 0.425 0.47 0.59 0.76];
% the corresponding vector for the coefficient of friction variable, Rf /c
Rfc = [1.3 1.6 1.75 1.9 2.3 3.1 4.4 7.3 8.7 10 16 36];
% the corresponding vector for the volumetric oil-flow rate, Q/ (RcnL)
Qc = [5.75 5.7 5.65 5.6 5.55 5.45 5.25 4.95 4.8 4.65 4.3 3.8];

% To interpolate the data, the MATLAB function csapi(X,Y) is used:
fhoc = csapi( S, hoc );
ffc = csapi( S, Rfc );
fQR = csapi( S, Qc );
fQs = csapi( S, Qsc );
fmu=csapi(S,mu_vector);
% The values of the interpolated data functions at Sc are calculated with:
% Sc = 0.2115
hc = fnval(fhoc, Sc);
fc = fnval(ffc, Sc);
Qc = fnval(fQR, Sc);
Qsc= fnval(fQs, Sc);
abs_vis=fnval(fmu,Sc);
>> % ho/c = 0.3122
>> % R f/c = 5.6888
>> % Q/(R c n L)=5.1009
>> % Qs/Q =0.8061

here this is some part of my code. ı take that values from the table and interpolate them to calculate some parameters for design of journal bearing. but on the table that ı shown there is no value for some parameters. but to ınterpolate matrices ı guess they should be same size. thats why ı wanted to learn what should ı put there. thank you in advance
