MATLAB: Efficient way to count the number of times a value changes to a particular value in an array array What is the best way to do the following: count=0; for i=2:length(x) if x(i)==1 && x(i-1)~=1 count=count+1; endend Best Answer sum(x(2:end)==1 & x(1:end-1)~=1) Related SolutionsMATLAB: Function similar to count One approach:A=randi([-1 1],1,100);%random data for -1,0 and 1cnt=sum(ismember(A,1));%counts the number of 1 in array A MATLAB: Count number of times value occurs Method for large a and b[u,~,j] = unique(b(:));[b, i] = ismember(a(:),u);c = accumarray(i(b),1,size(u));c = c(j)' Related QuestionRewrite function for loop in whileEfficient number occurence countCountCount number of times value appears in columnHow do i create a code which calculates the sum of number from 1 to x
