I am unable to label the y axis of a graph.

I have been trying to label the axis of a graph that I was plotting.

My code:

A = xlsread("GM_Time_History.xlsx");

x = A(:,1);

y = A(:,2);

i = (pi/2*9.81).*cumtrapz(y.^2);

figure;

plot(x,i);

xlabel('Time(sec)')

ilabel('AI')

The output graph only has the x axis labelled.

The error I am seeing is:

Unrecognized function or variable 'ilabel'.

Error in AriasIntensity (line 9)

ilabel('AI')

MATLAB does not contain an ilabel function. It looks like you want to use ylabel instead.

A = xlsread("GM_Time_History.xlsx");
x = A(:,1);
y = A(:,2);
i = (pi/2*9.81).*cumtrapz(y.^2);
figure;
plot(x,i);
xlabel('Time(sec)')
ylabel('AI')
