Description¶
The algorithm multiplies the Y values in a range of bins in a workspace by the factor given.
Usage¶
# Create a workspace with 100 bins
ws = CreateSampleWorkspace()
# Multiply the values in bins 25 to 75 by 3
res = MultiplyRange(ws,StartBin=25,EndBin=75,Factor=3.0)
# Check the result
# Get the Y values from the first spectra of the input and output workspaces
y = ws.readY(0)
yres = res.readY(0)
# Print out the ratios yres[i] / y[i] for bins with indices 20 to 30
print(yres[20:30] / y[20:30])
# Print out the ratios yres[i] / y[i] for bins with indices 70 to 80
print(yres[70:80] / y[70:80])
Output¶
[1. 1. 1. 1. 1. 3. 3. 3. 3. 3.]
[3. 3. 3. 3. 3. 3. 1. 1. 1. 1.]
