## Chapter 8 Code Examples

### MATLAB Code Examples

for j=1:4
j
end

for j=1:0.5:4
j
end

for j=1:4
for k=1:4
a(j,k)=j*k;
end
end
a

count=0;
while (count < 4 )
count
count=count+1;
end

### Python Code Examples

for j in range(4):
print(j)

import numpy as np
a = np.array([1,2,3])
for j in a:
print(j)

count = 0
while (count < 4):
print(count)
count = count + 1
