Help in finding the matrix

Hello! I have a vector of values, and I need to find their location in the matrix

% 1000x100 matrix
% 1x100 data

[Adam Danz]

Hint:

• ismember()
• find() (if you want subscripts)

[Lev Mihailov]

X=[1 2 3 4 5 6 7 
       112 123 123 124 216 125 125 
       1 2 3 4 5 6 229]
   Y=[112 123 123 124 216 125 229]

I took part of the code as it looks

[Adam Danz]

Now try to apply my hint. The documentation will help you understand how each function works.

[Andrei Bobrov]

In this case, what result do you expect?

[Lev Mihailov]

Z=ismember(Y,X);

When used along the entire length of the file, it produces a logical and all values ​​= 1

[Adam Danz]

That's because all element of Y are indeed in X. Try it the other way around. X as the first input.

You can use [row,col]=find( ) to get the location and use == to compare numbers
