Question

In MAtlab write a function such that

function newX = myBandPass(X, low, high)

a. INPUTS: i. A 2D matrix X ii. A low threshold, low. All values in newX must be greater than this. iii. A high threshold, high. All values in newX must be less than this.

b. FUNCTIONALITY: i. This function reads all elements of a matrix X, and sets them equal to zero if they are lower than low or higher than high.

c. OUTPUTS: i. newX: The matrix X after zeroing out elements below low and above high.

d. TEST CASE: >> A = [176.2360 171.0640 115.8960 162.4440; 207.2680 179.6840 0 0; 233.1280 190.0280 145.2040 146.9280; 248.6440 177.9600 181.4080 164.1680];

>> myBandPass(A, 175, 245)

ans = 176.2360 0 207.2680 179.6840 233.1280 190.0280 0 0 0 0 0 0 0 177.9600 181.4080 0

Explanation / Answer

function newX = myBandPass(X, low, high)

for i=1:size(X,1)

for j=1:size(X,2)
while (X(i,j)>high||X(i,j)<low)
newx(i,j)=0;
end
newx(i,j) = X(i,j);
end
end
end
newx
