### Matrix Operators And Their Descriptions In Matlab

**a(:);** This code creates a vector that includes succesively aligned row of “a” matrix elements.

**a(:,i);** The “j” row of matrix “a” will be indexed in Matlab.

**a(j,:);** The “j” column of matrix “a” will be indexed in Matlab.

**a(:,[i j]);** The “j” and “i” rows of matrix “a” will be indexed in Matlab.

**a([i j],:);** The “j” and “i” columns of matrix “a” will be indexed in Matlab.

**e=a:b:n; **An “e” matrix that will be created that has (a, a+b, a+2b,…,n) elements.

**length(a);** The row number of matrix “a” will be indexed.

**[m,n]=size(a);** The row and column number of matrix “a” will be indexed to “m” and “n” variables.

**max(a); **The biggest element of matrix “a” will be indexed in Matlab.

**min(a);** The smallest element of matrix “a” will be indexed in Matlab.

**[m,i]=max(a);** It indexes the biggest element a column vector “a” to “m”, and indexes its row number to “i” in Matlab.

**[m,i]=min(a); **It indexes the smallest element a column vector “a” to “m”, and indexes its row number to “i” in Matlab.

**sort(a); **The elements of matrix “a” will be sorted from biggest to smallest.

**a(:,i)=[];** It will delete the “i” column of matrix “a”.

**a(i,:)=[];** It will delete the “i” row of matrix “a”.

[…] some cases, you need to index the summation of elements in a matrix or vector in Matlab to use them in further calculations. This process is very easy in Matlan that […]
