simultaneous equation when a matrix has multiple sets inside

Hello,

I wanted to solve the simultaneous equation A=rand(3,3,51) and B=rand(3,1,51). I was trying to use the normal method C=A\B but this doesnt work. Was there a method to solve the 51 simultaneous equation using a function or loop as within A and B there are set of 51simultaneous equation.

Thanks

Rohan

Hi Rohan,

for loop can be used to solve this question.

for i=1:51        %% as there are 51 sets of simultaneous equations
    sol = mldivide(A(:,:,i),B(:,:,i));  %% alternatively it can be written as A(:,:,i)\B(:,:,i) 
    %%  x = A\B is an alternative way to execute x = mldivide(A,B)
    disp("The solution for " +i+"th simultaneous equation is ")
    disp(sol)
end

Refer to the mldivide documentation for more information on mldivide.
