2. xlabel(‘-2pi < x < 2pi’) ylabel(‘Sine and Cosine Values’)
3. legend({‘y = sin(x)’,’y = cos(x)’},’Location’,’southwest’)
4. k = sin(pi/2); title([‘sin(pi/2) = ‘ num2str(k)])

## How do I save a figure in MATLAB?

Click File > Generate Code…. The generated code displays in the MATLAB Editor. Save the code by clicking File > Save As. Generated files do not store the data necessary to recreate the graph, so you must supply the data arguments.

## How do I open a figure in MATLAB?

To display the figure, set visibility to ‘visible’ . If you do not want to display the figure, use the ‘invisible’ setting. You can use this option with any of the input argument combinations in the previous syntaxes. fig = openfig(___) returns the figure object.

## How do you label axis in Python?

## How do you print in MATLAB?

How do I print (output) in Matlab?
1. Type the name of a variable without a trailing semi-colon.
2. Use the “disp” function.
3. Use the “fprintf” function, which accepts a C printf-style formatting string.

Y = log10( X ) returns the common logarithm of each element in array X . The function accepts both real and complex inputs. For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ). For complex and negative real values of X , the log10 function returns complex values.
