Print out each matrix element

Hi, I would like to ask, how can I print out all element in unknow matrix dimention?

E.g,

User will input any matrix dimension like [100 200 300; 400 500 600] or [100 200; 300 400; 500 600; 700 800] and etc. Then I will need to take all element do some formula and print like below,

prinnt out:

100 * formula = answer

200 * formula = answer

300 * formula = answer

400 * formula = answer

500 * formula = answer

600 * formula = answer

700 * formula = answer

800 * formula = answer

It depends on what matrix that user key in, I did tried use for index =1:length(user input) or size(user input), but both them seems cannot achieve what I want.

Thanks in advance.

You need to read about fprintf.

formula = 3 ;
A = rand(3) ;
[m,n] = size(A) ;
for i = 1:m
    for j = 1:n
        ele = A(i,j) ; 
        val = ele*formula ; 
        fprintf('%f * %f = %f\n',ele,formula,val)
    end
end

0.477980 * 3.000000 = 1.433940
0.560227 * 3.000000 = 1.680680
0.591175 * 3.000000 = 1.773526
0.376574 * 3.000000 = 1.129721
0.612415 * 3.000000 = 1.837244
0.914196 * 3.000000 = 2.742589
0.593840 * 3.000000 = 1.781520
0.123138 * 3.000000 = 0.369415
0.404010 * 3.000000 = 1.212029
