Access a variable in Matlab using strcat












0














I have a situation where I want have many temperatures placed in column vectors, for example T101, T102, … and I would like to access these using a string cat command and place them in another vector. I created a simplified example to show what I am trying to achieve.



    clc

clear all

T102 = [5; 8; 20; 21];

P102 = [T102;1]

P102 = [strcat('T','102');1]


However, I am receiving an error for the second time I define P102 because it has now become the string 'T102' and I want it to become the variable T102 and not the string.

    Is the usage of these variables absolutely required? Because using a 2-D array would be a much better path forward.

I am not sure what you are trying to do and if it’s the right way.

But to answer your question you should use eval:



P102 = [eval(strcat('T','102'));1];
