renaming variable on workspace with string from cell of catalogue

i enter to a promt the name of my variable. that name is stored in a cell of catalogue. I want to use that name to rename my matrix after calculations. How can i do that?

this is my code:

    prompt = {'Enter start time:','Enter stop time:','Enter segment name'};
    dlg_title = 'Segment signal';
    num_lines = 1;
    def = {'','','r1s1'};%default values of promt where the first is start time, stop time and segment name
    input = inputdlg(prompt,dlg_title,num_lines,def); %add entered promt to cell
    input1=str2num(char(input(1:2))); %convert the 2 parameters to number
    %start=472; %start time of the segment
    %stop=607; %stop time of the segment
    list=(input1(1)<t1)&(t1<input1(2));%get rows where condition is met
    [,list1]=find(list>0);%get id of the rows where condition is met
    % get values for the segment
    p(:,1)=t1(list1); %get time
    p(:,2)=acc1(list1,3); %get value
    %i want to rename p to r1s1 or whatever i enter into the promt

You don't really want to do that! For the same reasons that you don't want to create A1 A2 ... An in a loop

If you actually want to do this, which, like I said, you don't (!), you can use eval()

look at my code, i used eval to no success

I am looking at your code, and I see no call to eval()

@Sean: Exactly. +1

@effess: Creating variables dynamically is a bad programming style. Please search for the other thousands of posts concerning the avoidance of EVAL in this forum to learn more.

@Sean

str = [input(3),'= p;'];

eval(str);

that how i was trying to rename variable.

[Walter Roberson]

input(3) is a cell array, not a string. Use input{3}

[DuckDuck]

yep that was the thing :)

i accept your answer.
