To find array elements that meet a condition, use find in conjunction with a relational expression. For example, find(X<5) returns the linear indices to the elements in X that are less than 5 . To directly find the elements in X that satisfy the condition X<5 , use X(X<5) .
27 paź 2013 · Here is a solution based on accumarray that will work even if a row is all zeros. A = [ -1 0 -2 0 0. 2 8 0 1 0. 0 0 3 0 -2. 0 -3 2 0 0. 1 2 0 0 -4]; [r,c] = find(A); %# for every row, take the minimum column index and put NaN if none is found.
4 paź 2014 · this is simple :) name the matrix A (for example) then : m=min(A(A>0)); m returns the non zero minumum
Use nonzeros, nnz, and find to locate and count nonzero matrix elements. Create a 10-by-10 random sparse matrix with 7% density of nonzeros. A = sprand(10,10,0.07); Use nonzeros to find the values of the nonzero elements. v = nonzeros(A) v = 7×1. 0.9595.
Displaying Specific Rows with Non-zero values. Learn more about display, fprintf I created the following code to create variable names for my solution (Zvalues) to an MILP problem.
I have a matrix of 1x1177 and I wanted to display all the nonzero values with the array and the location of them. I am able to get the location of them using: find (matrixOne) But I also need the values to be displayed.
