To nd the maximum value, replace the call to min with max. 14 5.5 Repeating/tiling vectors without repmat As of MATLAB 5.3 (R11), the repmat function is implemented as an m- le rather than as a built-in function.
A >= B returns a logical array with elements set to logical 1 (true) where A is greater than or equal to B; otherwise, the element is logical 0 (false).The test compares only the real part of numeric arrays. ge returns logical 0 (false) where A or B have NaN or undefined categorical elements.

You can use regionfill to remove objects in an image or to replace invalid pixel values using ... matrix of size greater than or equal to 3-by-3. ... in the MATLAB ... Use logical indexing instead: a (a == 2) = -5. In case of searching whether a matrix is equal to inf you should use. a (isinf (a)) = -5. The general case is: Mat (boolMask) = val. where Mat is your matrix, boolMask is another matrix of logical values, and val is the assignment value. Share.Replace Values That Meet a Condition. Sometimes it is useful to simultaneously change the values of several existing array elements. Use logical indexing with a simple assignment statement to replace the values in an array that meet a condition. Replace all values in A that are greater than 10 with the number 10.Using the colon operator : and other methods for accessing information in a matrix.

Oct 05, 2012 · I have a matrix A. Now I want to find the number of elements greater than 5 and their corresponding indices. How to solve this in matlab without using for loop? For example if A = [1 4 6 8 9 5 6 ... Test Complex Numbers. Open Live Script. Create a vector of complex numbers. A = [1+i 2-2i 1+3i 1-2i 5-i]; Find the values that are greater than 2. A (A > 2) ans = 5.0000 - 1.0000i. gt compares only the real part of the elements in A. Use abs to find which elements are outside a radius of 2 from the origin.A > B returns a logical array with elements set to logical 1 ( true) where A is greater than B; otherwise, the element is logical 0 ( false ). The test compares only the real part of numeric arrays. gt returns logical 0 ( false) where A or B have NaN or undefined categorical elements. gt (A,B) is an alternate way to execute A > B, but is rarely ...

Oct 28, 2021 · Convert it to a grayscale Image if read image is an RGB Image. Calculate a threshold value, T. Create a new Image Array (say ‘binary’) with the same number of rows and columns as original image array, containing all elements as 0 (zero). Assign 1 to binary (i, j), if gray level pixel at (i, j) is greater than or equal to the threshold value ...

Step 1: On current visible worksheet, right click on sheet name tab to load Sheet management menu. Select View Code, Microsoft Visual Basic for Applications window pops up. Is there a way in MATLAB to select from a matrix with a range of values in column A(:,1) where: B = select from A where A(:,1)<20070000. Cannot find this logic anywhere. EDIT: I need to select these indicated rows from all columns of A.

A=find (d (:,4)==0); % create a table that will include only the values that had 0 or 1 at their erd column and give me in the two other columns the values % d1=new table. % d= original table. % A=table with #nodes containing the nodes with 0. % 1:2= give the values for the nodes with 0 and give columns 1&2.Apr 02, 2011 · In logical indexing, you use a single, logical array for the matrix subscript. MATLAB extracts the matrix elements corresponding to the nonzero values of the logical array. The output is always in the form of a column vector. For example, A(A > 12) extracts all the elements of A that are greater than 12.

Replace 'greater than' values in a matrix. Learn more about matrix, replace, greater than;Replace the values of the first column that are greater than 5 by 0. In the second column, if the values are within the range 121-130, replace them by 0. If they are within the range 131-140, replace by 1, 141-150 by 2, 151-160 by 3, etc. So the desired result matrix would be:
