i design a GUI.... and inside a button i give "clear all" to clear all variables as it takes lots of space... but the gui design tables and static text and axes and all the other design items also gets cleared.... how to clear only variables without clearing the gui design....

Why don't you just clear your variables by listing them after clear, like
clear var1 var2

Elysi - if there are specific variables that you want cleared, then you can clear them by name:
x = zeros(100,100);
y = zeros(1000,33);
z = ones(32,32);
% do some stuff
% clear just x and y only
clear x y;
Type help clear from at the command window for more details.

Elysi - please provide a sample of your code that describes where all these variables are coming from i.e. those that you wish to clear, and your use of the clear all command. I still don't understand why you have so many variables that need to be cleared and why you are invoking the clear all command within your code.
Or, you can prefix all of your GUI controls with a gui_ prefix, and then execute the clear command on anything but those variables. For example, in the Command Window type:
clear all; % clear all existing variables and other
x=123; % create five different variables
y=zeros(12,12);
z=cell(1,34);
gui_text1=123.4;
gui_text2=345.3;
Now you can clear all but the gui_ variables with the following command:
clear -regexp ^(?!gui_)\w
