MATLAB: Printing Results out of a for Loop

for loopfunctionminprint

I have Written a Small Function that Returns the Absolute Difference Between the Max and Min Elements of Each Row in a Matrix and Assigns the Results to the output "rows_diff" as Row Vector and Also Gets the Diff. Between the Max and Min of Whole Matrix in "tot_diff"

All what I want to Know is How to Print Out the Results of the for Loop Returning them in "rows_diff" as row vector not just the Last Result as the Case with this Version of the Function:-

function [rows_diff, tot_diff] = minimax(M)

a = size(M,1);

for i = 1:a

rows_diff = abs(max(M(i,:)) – min(M(i,:)));

end

tot_diff = max(M(:)) – min(M(:));

Best Answer

rows_diff = abs(max(M(i,:)) - min(M(i,:)));

This overwrites the value of rows_diff each time. This is ok if you just want to print it out, but to store it (which seems like you want to) you need:

rows_diff(i) = abs(max(M(i,:)) - min(M(i,:)));

to print this value, in your loop place a fprintf

fprintf('Value of rows_diff = %f\n',rows_diff(i))

MATLAB: Creating matrix w.r.t. rows number of another matrix

E.g., a method using a cell array

u = unique(col_row(:,1));
n = numel(u);
result = cell(max(u),1);
for k=1:n
    result{u(k)} = data(col_row(col_row(:,1)==u(k),2));
end

This assumes that all of the "row" numbers are positive integers. If they are not, then one could do this instead

u = unique(col_row(:,1));
n = numel(u);
result = cell(n,1);
for k=1:n
    result{k} = data(col_row(col_row(:,1)==u(k),2));
end

MATLAB: Write a function called minimax that takes M, a matrix input argument and returns mmr, a row vector containing the absolute values of the difference between the maximum and minimum valued elements in each row. As a second output argument called mmm

function [mmr,mmm] = minimax(M)
a=max(M');
b=min(M');
mmr=a-b;
c=max(a);
d=min(b);
mmm=c-d;
end
% This is what i came up with. Please give a upthumb if it works.
