Max Min value in every column Of Matrix

I Have a code that gives me some output in my command window as a 9 by 80 matrix. I want that when I run the program and it gives me output in the command window, the max and min value should stand outin some way in each column so that I don't have to find them by looking at each row and each column. They could be either bold or underlined or coloured . I dont know how to do it. Or is it even possible?. If not, can you suggest any other way?

bold or underlined in what? There are numerous ways to display data, but by default it is not displayed at all, it is just in a variable.

Do you mean you have a UI with a table of these values or do you want the min and max to be highlighted in the Variable editor?

As far as I know the latter is not possible.

is there no way to get max and min values out of matrices of my output file??

Your request in not clear, and you keep changing what you are asking for.

In your original question you state that "code that gives me some output as a 9 by 80 matrix": this implies that the matrix exists in MATLAB's workspace. Now you write that the matrices are in "my output file". So now we have to read a file as well? Where is this data, in MATLAB's workspace or in a file? Are we supposed to be able to read your computer screen to know this?

Your original question asked to display some text in an undisclosed location, "either bold or underlined". However you do not say if this is to be printed in the command window, in a GUI or figure, or placed in an image, saved in a file, or printed somewhere else entirely different. So without knowing where you want this "underlined" text, it is difficult to tell you how to do it.

For your latest comment, have you tried reading the min and max documentation?

I recommend that you read this thoroughly:

The 'ix' vector in

   [~,ix] = max(A,[],1)

will give the row (1st) index of the maximum value in each column of A, and similarly for the minimums. You should be able to figure out how to use that information to create your display.

Sorry guys I was not clear. I have edited my question.

That scenario is exactly what my answer addresses! Either you modify your code or, if you cannot do that, capture the output with evalc and print it with a function according to my answer.

Thanks per isakson

See per Isakson's Answer, it actually answers the question asked.

[Stalin Samuel]

here i have given a example for you

   a = [1:5;6:10;11:15;16:20;21:25]

a=a'
[x y] = size(a)
axis([0 x 0 y])
for i=1:x
for j=1:y
if a(i,j)==max(a(i,:))
text(i,j,[ num2str( a(i,j))],'Fontsize',30)
hold on
else
text(i,j,[ num2str( a(i,j))],'Fontsize',20)
hold on
end
end
end

Thanks Stalin

@Stalin Samuel: Note that you should not use i or j as loop variable names, as these are the names of the inbuilt imaginary unit.

Also note that consistent indentation makes code easier to follow. Please consider using the MATLAB Editor's default code indentation and formatting in order to make your cod more readable.

Answer 2

[per isakson]

"the max and min value should stand out in each column" &nbsp AKAIK: formatting the output in the command window is not available in the standard Matlab. However, I think it's a good idea and that it can be realized with a small function based on one of these File Exchange contributions

• cprintf - display formatted colored text in the Command Window by Yair Altman
• displaytable by Matt Caywood
• cprintf: a pedestrian ND array formatting and display utility by us

"is there no way to get max and min values out of matrices of my output file??" &nbsp I don't understand this question. The word "file" doesn't appear in the original question. There are functions to calculate min and max.
