just recommended to another MATLAB CENTRAL user to try the class TABLE. The starter example from MATLAB help:

LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];

T = table(Age,Height,Weight,BloodPressure,'RowNames',LastName)

modify the above example accordingly to build your telephone directory.

Save your telephone directory to a .mat file with

save('phonedir_filename.mat','T')

And bring it back to workspace in new MATLAB session with

load phonedir_filename.mat

You can also have MATLAB writing and reading from a directory stored in a support Excel file with xlsread and xlswrite

this answer is not working. it is saying Undefined function or method 'table' for input arguments of type 'cell'. on executing the program

Aditya, the code works, It's the standard example from MATLAB help. MATLAB 2015. What Matlab version are you using. There are earlier versions of Matlab that do not have the class table implemented, the command table() is not recognized.

table class was introduced in R2013b, if you upgrade the command table will work. Alternatively, you can build your own structure, a table is just a specific type of structure.
