Matrix Operators And Their Descriptions In Matlab

Examples of some of matrix operators 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”.
