In-Depth Information

length Returns the number of elements in a vector or string.

length('abcde')

limit Finds a two-sided limit, if it exists. Use 'right' or 'left' for one-sided

limits.

syms x; limit(sin(x)/x, x, 0)

syms x; limit(1/x, x, Inf, 'left')

linspace Generates a vector of linearly spaced points.

linspace(0, 2*pi, 30)

load Loads Workspace variables from a disk file.

load filename

lookfor Searches for a specified string in the first line of all M-files found in the

MATLAB path.

lookfor ode

ls Lists files in the current working directory. Similar to dir .

maple String access to the Maple kernel; generally is used in the form

maple('function', 'arg') . Not available in the Student Version.

maple('help', 'csgn')

max Computes the arithmetic maximum of the entries of a vector.

X=[351-623-56100]; max(X)

mean Computes the arithmetic average of the entries of a vector.

X=[351-623-56100]; mean(X)

symsxyz;X=[xyz];mean(X)

median Computes the arithmetic median of the entries of a vector.

X=[351-623-56100]; median(X)

min Computes the arithmetic minimum of the entries of a vector.

X=[351-623-56100]; min(X)
