problem using the find function
显示 更早的评论
hi, i'm trying to use the find function to locate specific values form matrix array and to remove them (as you can see in the attached m-file) https://www.dropbox.com/s/bcynkiblh7n8tr5/check_values_s_ds_script.m
i use the function like this:
[row,col] = find(resault>0.899 & resault < 1);
but still i find values that are greater then 1 (some are even 50) what am i doing wrong?

ok but the find function dosn't seem to find only the values between 0.889 to 1, you can see in the plot (colorbar) that i recive the location of a variable that is way greater then 1.

This is not true. How can we see it in a figure?

the colorbar shows the number 35 in red as the highest value also i can see red dots and in the matrix on those locations (columns and rows) there are number greater then 1

I don't know how you got those figures, but I can assure you that
row,col] = find(resault>0.899 & resault < 1)
will find only location of numbers that are between 0.899 and 1

row and col are the indices in the matrix which have the value you need. Find function just finds the indices which satisfy the condition, however find function does not replaces those values.

What you want is
resault(resault>0.899 & resault < 1)
Maybe what you mean by remove them
resault(resault>0.899 & resault < 1)=0
Removing an element doesn't mean set it to zero. Also you can't remove a element from a nxm matrix, you can remove an entire column or row.

or
resault(resault>0.899 & resault < 1) = nan;
