What does Semilogx do in Matlab?

semilogx(Y) creates a plot using a base 10 logarithmic scale for the x-axis and a linear scale for the y-axis. It plots the columns of Y versus their index if Y contains real numbers.

What is semi logy?

semilogy( X , Y ) plots x- and y-coordinates using a linear scale on the x-axis and a base-10 logarithmic scale on the y-axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length.

How do you write log2 in Matlab?

Description. Y = log2( X ) returns the logarithm to the base 2 of X such that 2Y = X. If X is an array, then log2 acts element-wise on X . [ F , E ] = log2( X ) returns arrays of mantissas and exponents, F and E , such that X = F ⋅ 2 E .

What is set GCA in Matlab?

Description. example. ax = gca returns the current axes (or standalone visualization) in the current figure. Use ax to get and set properties of the current axes. If there are no axes or charts in the current figure, then gca creates a Cartesian axes object.

How do you read a log scale?

Locate the position along the logarithmic scale y-axis. (ten million), the lines represent divisions of 1,000,000’s. . Even though, on a standard linear scale, 4,000,000 is less than halfway between 1,000,000 and 10,000,000, because of the logarithmic scale, it actually appears slightly more than halfway.

What is the value of log2?

The value of log 2, to the base 10, is 0.301. The log function or logarithm function is used in most mathematical problems that hold the exponential functions.

What is GCA GCF?

gca and gcf The axis has properties that describe the characteristics of your axes. To list all properties of the figure, you can type get(gcf) (which stands for get current figure). To list all properties of the axis, you can type get(gca) (which stands for get current axis).

What is Xtick MATLAB?

xticks( ticks ) sets the x-axis tick values, which are the locations along the x-axis where the tick marks appear. Specify ticks as a vector of increasing values; for example, [0 2 4 6] . This command affects the current axes. xt = xticks returns the current x-axis tick values as a vector.
