Convert rows of a matrix to vectors

Question

I have a matrix lets say:

A=[1 2 1; 5 6 7; 7 8 9]

and I want to extract its rows in the following format:

x_1=[1 2 1] x_2=[5          


        

Answer 1

You can try the following:

m = size(A,1);

for i=1:m
    % set the variable name
    varName = sprintf('x_%d',i);

    % create and assign the variable in the base workspace
    assignin('base',varName,A(i,:));
end 

The code iterates through every row of A, creates the variable name (as per your format) and then assigns a variable in the MATLAB base workspace ('base') with its data being the ith row of A.

If doing this from a function, rather than using 'base' use 'caller' to indicate that the variables should be created in the workspace of the function.
