Estimate the maximum value among three consecutive values in a vector

Hello, I need to do some calculation on each value for each vector. For example, the vector A may contain hundreds of acceleration values:

A=[0.18, 0.01, -0.15, 0.08, .25, 0.12, ......]

I need to abtain a new vector which contains the max value of each three consecutive values of the vector like this:

B=[max(0.18,0.01,-0.15), max(0.01, -0.15,0.08), max(-0.15,0.08,0.25) ...... end=length signal(A)]

I would appreciate your help

Best

A=[0.18, 0.01, -0.15, 0.08, .25, 0.12];
output = movmax(A,3)

output = 1×6

0.1800 0.1800 0.0800 0.2500 0.2500 0.2500

Note that @Dyuman Joshi's answer illustrates that the movmax function accepts arguments that will affect how you want to handle the endpoints.

%Random data for example
x = 1:10;
y = movmax(x,3,'Endpoints','discard')

y = 1×8

3 4 5 6 7 8 9 10
