round Round towards nearest integer. round(X) rounds the elements of X to the nearest integers. See also floor, ceil, fix. Syntax Y = round(X) Description Y = round(X) rounds the elements of X to the nearest integers. For complex X, the imaginary and real parts are rounded independently. E...

Defining a Vector Matlab is a software package that makes it easier for you to enter matrices and vectors, and manipulate them. The interface follows a language that is designed to look a lot like the notation use in linear algebra. In the following tutorial, we will discuss some of the basics of w...

Construct array with accumulation Syntax A = accumarray(subs,val) A = accumarray(subs,val,sz) A = accumarray(subs,val,sz,fun) A = accumarray(subs,val,sz,fun,fillval) A = accumarray(subs,val,sz,fun,fillval,issparse) A = accumarray({subs1, subs2, …}, val, …) Description accumarray groups e...

Absolute value and complex magnitude Syntax 1 abs(X) Description abs(X) returns an array Y such that each element of Y is the absolute value of the corresponding element of X. If X is complex, abs(X) returns the complex modulus (magnitude), which is the same as 1 sqrt(real(X)....

plot Linear plot. plot(X,Y) plots vector Y versus vector X. If X or Y is a matrix, then the vector is plotted versus the rows or columns of the matrix, whichever line up. If X is a scalar and Y is a vector, length(Y) disconnected points are plotted. plot(Y) plots the columns...
